The Champions League returns this week with a matchup between the top two teams in our European Power Rankings, as Barcelona travels to Paris to face the two-time defending European champions, PSG.

Behind those two, Bayern Munich and Arsenal are also preparing for a heavyweight Champions League matchup, Manchester City continues its perfect Premier League start despite a setback in Europe, and Real Madrid is beginning to find its rhythm under José Mourinho.

The biggest risers this week are Brighton and Brentford, while Manchester United and Napoli are heading in the wrong direction.

Match of the Week: Barcelona vs. PSG

Tuesday, October 20 | 3:00 PM ET | Paramount+

There isn't a more intriguing matchup in European soccer right now.

The two best teams in Europe right now, both playing entertaining, attacking styles and scoring loads of goals.

Barcelona enters the game having won all 11 competitive matches this season, including nine straight victories in La Liga, a new club record to start a league campaign. Hansi Flick's team has scored an absurd 48 goals in those 11 games, with Raphinha and Lamine Yamal leading an attack that somehow looks even more dangerous without a conventional striker.

PSG has been nearly as impressive. Luis Enrique's team is coming off a 4-2 victory at Manchester City, perhaps the most impressive result of the young European season. The defending champions have won both Champions League matches by a combined 10-3 score and remain the team everyone else is trying to dethrone.

The tactical matchup should be fascinating because these teams approach the game with similar philosophies. Both want to press aggressively, dominate the midfield and attack before the opposition can organize its defense.

Barcelona's biggest advantage may be its midfield, where Rodri and Pedri provide an outstanding combination of defensive security and technical control. However, PSG's Vitinha, João Neves and Fabián Ruiz are more than capable of matching them.

The matchup on the wings could be decisive. Lamine Yamal is taking his game to a new level this season, with an absolutely ridiculous goal over the weekend. PSG will be missing star left back Nuno Mendes, creating a potential opening for Yamal to attack. Barcelona, meanwhile, have some defensive injuries of their own, with Jules Koundé, Eric García and Andreas Christensen unavailable. That is not ideal against an attacking group featuring Ousmane Dembélé, Khvicha Kvaratskhelia and Désiré Doué.

Barcelona's aggressive defensive line has been vulnerable to quick attacks before, and PSG is one of the few teams with enough technical ability to play through the initial press and enough speed to exploit the resulting space.

For all of Barcelona's spectacular attacking performances, there is a reasonable question about the quality of its early La Liga opponents. Saturday’s 5–2 victory at Real Betis was Barcelona's first league win against a team currently in La Liga's top four.

PSG represents a considerably tougher test.

A single October match won't determine which team is best in Europe, especially with Barcelona's defensive absences. But it should provide an excellent early measuring stick for the two leading Champions League contenders.

European Power Rankings: Top 20

1. Barcelona (No Change)

Barcelona continues to look like the most complete attacking team in Europe. The 4-1 Champions League victory at Galatasaray and 5-2 win at Real Betis extended its perfect start, with Lamine Yamal looking increasingly unstoppable.

The most encouraging development has been how naturally the attack has adapted without a traditional striker. Even with Raphina missing most of the two games this week, they rolled on with Dani Olmo slotting into the false-nine forward role against Galatasaray and the team barely missing a beat.

There are still questions about defending transitions, especially with the mounting injuries, but no other team has combined this level of attacking production with such consistent results.

2. Paris Saint-Germain (Up 2)

PSG makes the strongest argument for taking the top spot after going to Manchester City and winning 4-2.

The performance was a reminder of how difficult Luis Enrique's team is to handle when its midfield controls the tempo and the attackers begin interchanging positions. PSG can overwhelm weaker opponents through possession, but it also has the speed and technical quality to punish elite teams that press too aggressively.

The Parisians followed the City result with a 3-1 win at Strasbourg. Tuesday's game against Barcelona gives them the opportunity to establish themselves as Europe's clear No. 1.

3. Bayern Munich (No Change)

Bayern's week was a strange one.

Vincent Kompany's went down two goals before coming back for a 3-3 Champions League draw at Viking, with Michael Olise's red card contributing to the disappointing result. But Bayern returned home and absolutely demolished RB Leipzig 6-1 in the Bundesliga this weekend.

Luis Díaz scored a hat trick against Leipzig, while Harry Kane again demonstrated how much more he provides than conventional center-forward finishing.

Bayern is back atop the Bundesliga and remains one of Europe's most dangerous attacking teams. The concern is that its aggressive defensive approach can occasionally become vulnerable when opponents escape the initial pressure.

Wednesday's meeting with Arsenal should provide another excellent test.

4. Arsenal (Down 2)

Dropping Arsenal two spots is more about PSG's rise and the quality of competition than a significant deterioration in Arsenal's performances.

The defending Premier League champions followed their disappointing loss at Brighton with a comfortable 3-0 Champions League win over Lille and a narrow 1-0 victory at Nottingham Forest.

Mikel Arteta's team remains exceptionally difficult to break down, but the attack hasn't consistently reached the level of Barcelona, PSG or Bayern. The continued struggle to integrate Eberechi Eze into the attacking structure is becoming a legitimate concern.

Arsenal's defensive organization gives it a chance against anybody. The question is whether it has enough attacking variety to impose itself against Europe's very best.

5. Manchester City (Up 1)

City's 4-2 home loss to PSG was a reality check, but it shouldn't erase what Enzo Maresca has accomplished in the Premier League.

City has won its first seven league matches, including a 3-0 victory at Liverpool and a 3-2 win over Ipswich this weekend. Erling Haaland continues to score at a ridiculous pace, with 12 goals in his last eight appearances across competitions.

The more interesting story is how Maresca is rebuilding the midfield after Rodri's departure. Young Ayyoub Bouaddi looked impressive against Ipswich, providing another option in a group still finding its ideal balance.

The PSG match exposed areas where City remains vulnerable against elite opposition, but its domestic form is difficult to argue with.

6. Real Madrid (Up 1)

Real Madrid continues to look increasingly dangerous under José Mourinho.

The 4-3 Champions League victory at Roma required some familiar Madrid resilience, but Sunday's 4-1 victory over Sevilla was a more convincing display of its attacking potential.

Kylian Mbappé scored twice, Arda Güler was excellent orchestrating the attack, and Yan Diomandé continues to provide another explosive option.

Madrid still doesn't control matches as consistently as Barcelona, and the midfield balance remains a work in progress. However, Mourinho is gradually finding ways to get his collection of stars into dangerous positions without asking every possession to be an elaborate buildup.

Next weekend's El Clásico will be an important test of just how far that progress has come.

7. Inter Milan (Down 2)

Inter remains the strongest team in Italy, but its Champions League performance against Club Brugge was concerning.

Cristian Chivu's team allowed four goals at home in a shocking 4-3 defeat, repeatedly struggling to contain Brugge's attackers despite getting two goals from Lautaro Martínez.

To its credit, Inter responded by coming from behind to beat Bologna 3-1, extending its unbeaten Serie A start and maintaining first place.

The attacking quality is clearly there, and Inter has enough experience to recover from an ugly European night. However, a team with ambitions of winning the Champions League cannot defend that poorly against opposition it should comfortably handle.

8. Chelsea (No Change)

Chelsea has quietly put together one of the better recent stretches in the Premier League.

Xabi Alonso's team followed a 5-1 demolition of Bournemouth with a comfortable 2-0 victory at Everton. The results suggest that Chelsea's expensive collection of attacking talent is beginning to develop more cohesion.

Cole Palmer remains the central creative figure, but the encouraging development is that Chelsea is increasingly finding contributions from the players around him.

There are still defensive questions, particularly against teams capable of playing through Chelsea's press, but the overall trajectory is positive.

9. Atlético Madrid (Up 1)

Atlético has become one of the more impressive teams in Spain after a relatively uneven start.

Diego Simeone's team followed its derby victory over Real Madrid with a convincing 2-0 Champions League win against Manchester United, then collected another three points with a 1-0 victory at Espanyol.

Johnny Cardoso's emergence in midfield has been particularly encouraging. He provides another player capable of winning possession and moving the ball forward without sacrificing defensive stability.

Atlético remains five points behind Barcelona in La Liga, but it is increasingly playing like a legitimate contender rather than simply a team hoping the big two stumble.

10. Liverpool (Up 1)

Liverpool has been difficult to evaluate because the attacking talent is obvious, but the performances remain inconsistent.

Andoni Iraola's team suffered a comprehensive 3-0 defeat to Manchester City before recovering with a wild 6-3 Champions League win at LASK and a 2-1 victory at Brentford.

Florian Wirtz's performance against Brentford was encouraging. He created nine chances and increasingly took responsibility for progressing the attack, particularly after Brentford went down to ten men.

There are signs the connections between Liverpool's attacking players are improving. However, the defensive structure still looks vulnerable when opponents can bypass the initial pressure, particularly against teams with City's quality.

11. Roma (Up 1)

Roma continues to look like a legitimate challenger to Inter in Serie A.

Gian Piero Gasperini's team pushed Real Madrid to the limit in a 4-3 Champions League defeat before responding with a 2-0 win over Genoa. Roma sits third in Italy, just two points behind Inter and Lazio.

The biggest positive is the development of a coherent attacking identity. Roma is willing to commit players forward and use aggressive movement to create opportunities rather than relying entirely on isolated individual brilliance.

The Madrid defeat demonstrated there is still a gap to Europe's elite, particularly when Roma gets stretched defensively. But this is an interesting team with room to improve.

12. Brighton (Up 3)

Brighton may be the most interesting team in England outside the traditional powers.

After beating Arsenal before the international break, Fabian Hürzeler's team returned with a 5-0 demolition of Crystal Palace that was essentially over after ten minutes.

Diego Gómez scored an outrageous goal from near midfield, while Pascal Groß continues to be one of the most influential midfielders in the league.

Brighton has scored 23 goals through seven Premier League matches and demonstrated impressive attacking depth, with 11 different players contributing goals.

The question is whether Brighton can maintain this level over a full season. But the combination of aggressive pressing, intelligent midfield movement and contributions throughout the lineup gives it a realistic opportunity to challenge for Champions League qualification.

13. Borussia Dortmund (Up 1)

Dortmund remains near the top of the Bundesliga, but the last week hasn't been particularly convincing.

A disappointing 1-0 Champions League defeat at Bodø/Glimt was followed by a scoreless draw at Union Berlin. Dortmund has now failed to score in consecutive matches.

Niko Kovač's team has generally been defensively solid, and it remains level on points with Bayern in Germany. However, its attacking output is becoming a concern.

Dortmund belongs in this group based on its overall quality and league position, but it needs to rediscover some creativity before the gap between itself and Bayern becomes more obvious.

14. Brentford (Up 3)

Brentford continues to make a compelling case that its outstanding start is sustainable.

The 2-1 loss to Liverpool was disappointing, particularly because Brentford had taken the lead before Yehor Yarmolyuk's red card changed the match.

There is some validity to arguing the result should be discounted. Brentford was competitive with one of the league's most talented teams until being reduced to ten men, then still made Liverpool work for the victory.

This is a well-organized team with a clear understanding of how to win the ball and attack quickly. Brentford may not have the individual talent of the clubs above it, but it is consistently getting more out of its roster than several more expensive opponents.

15. Napoli (Down 2)

Napoli is heading in the wrong direction.

A 3-1 Champions League defeat at Villarreal was followed by an embarrassing 1-0 loss at Venezia, a team that had lost its first six Serie A games.

Napoli had opportunities to rescue the Venezia match, including a penalty that Kevin De Bruyne failed to convert, but the broader performance was concerning.

The attacking talent is still considerable, but Napoli is struggling to consistently turn possession into dangerous opportunities. Its inability to control matches against theoretically weaker opponents raises questions about how far this team can go in Europe.

16. Manchester United (Down 7)

No team takes a bigger fall in this edition.

Manchester United's difficult start continued with a 2-0 Champions League loss at Atlético Madrid and a 1-1 draw at Leeds United.

Michael Carrick's team has invested heavily in rebuilding the squad, but the results remain underwhelming. Carlos Baleba and Andrey Santos showed encouraging signs as a midfield partnership against Leeds, but United still struggles to consistently connect its buildup to its collection of attacking players.

The concern isn't simply that United has dropped points. It is that the team still looks a long way from consistently competing with the top clubs despite having enough individual talent to expect much better.

17. Lazio (New)

Lazio may be the biggest surprise in Serie A this season, and Gennaro Gattuso's team is making an increasingly convincing case that its outstanding start is no fluke.

The Biancocelesti followed a 3-1 victory over Monza with a statement 3-0 win at Juventus, extending their unbeaten league start to seven matches and moving level with Inter atop the table. Gustav Isaksen has emerged as an important attacking threat, while Mattia Zaccagni and Nuno Tavares provide creativity and width.

Gattuso deserves considerable credit for building a team that is organized defensively without sacrificing its ability to attack quickly. The question is whether Lazio has enough depth and individual quality to sustain a title challenge over a full season. But with six wins from seven league matches, it has earned a place among Europe's top 20.

18. Aston Villa (Up 2)

Aston Villa is finally beginning to resemble the team Unai Emery hoped to build.

After a disastrous start to the Premier League season, Villa produced a remarkable 6-0 Champions League victory over Fenerbahçe, then followed it with an impressive 1-0 road win at Newcastle.

Those results suggest the team is beginning to develop some much-needed defensive stability and attacking confidence.

Villa still has plenty of work to do to erase its early league struggles, but the talent is there to make a significant climb if this improvement continues.

19. Bournemouth (Down 1)

Bournemouth continues to alternate between impressive performances and uncomfortable defeats.

The 5-1 loss at Chelsea exposed some significant defensive weaknesses, but Sunday's 2-0 victory over Sunderland was an encouraging response.

Bournemouth remains dangerous when it can press, recover possession and attack before opponents reorganize. The problem is that its defensive approach can become vulnerable against teams with enough quality to bypass that pressure.

There is still a strong foundation here, but Bournemouth needs to become more consistent before moving higher.

20. Juventus (Down 4)

Juventus is running out of excuses.

Luciano Spalletti's team followed a disappointing draw at Cagliari with an ugly 3-0 home loss to Lazio. The performance was arguably even worse than the score, with Juventus struggling to play through Lazio's pressure and generating very little attacking danger.

Spalletti acknowledged afterward that his team lacked both control and ideas.

Juventus remains talented enough to recover, but the early evidence suggests it is considerably farther from Italy's best teams than expected. For now, the Bianconeri are hanging onto a place in the top 20 largely on the strength of their individual talent rather than anything they've demonstrated on the pitch.

Looking Ahead

This week could create the first major shakeup at the top of the rankings.

Barcelona and PSG meet Tuesday in Paris, while Bayern hosts Arsenal on Wednesday. Those two matches feature all four of our top-ranked teams and should provide considerably more insight into the European hierarchy than another round of comfortable domestic victories.

Meanwhile, Real Madrid has a Champions League match against Leipzig before Sunday's El Clásico against Barcelona.

For the first time this season, Europe's elite teams are beginning to face each other regularly rather than accumulating impressive results against weaker opposition.

We should have a much clearer picture of who belongs at the top by this time next week.
