Champions League power rankings: Who has performed best?
How the rankings work
We've created an algorithm to measure and grade every player's performance in Champions League matches this season, including what they have contributed individually and how their team performed in their area of the pitch. The data is also adjusted for home advantage and based on the relative strength of the opposition.
After every round of matches we'll be updating the rankings to track which players have had the most influence on this season's competition. All scores are out of a maximum of 10, with attacking and defensive players ranked separately.
Cristiano Ronaldo may be approaching the end of his career but he still performs like a man who was born to dominate the Champions League. An ever-present for Real Madrid this season, he has scored in each of his eight appearances and had a hand in 14 goals overall, putting him in a class of his own at the top of the attacking rankings.
Some distance behind him are three Liverpool players, but not led by the man you would expect. Mohamed Salah may be lighting up the Premier League but he is only eighth among Champions League attackers. James Milner surprisingly leads the way for the Reds, edging out Sadio Mane and Roberto Firmino thanks to having provided six assists - one every 72 minutes - from much deeper positions.
Mane has scored or assisted once every 62 minutes in this season's tournament - most memorably his hat-trick in Porto - narrowly edging out his team-mate Firmino who has been involved in a goal every 63 minutes. The Brazilian's contribution is also downweighted slightly due to playing in a more advanced position, and also having three of the goals he was involved in come against lowly Maribor.
Wissam Ben Yedder is a new entry in the top 10 after his stunning brace in a cameo from the bench against Manchester United, having missed the first leg entirely. Three Manchester City players also make the cut, with Kevin De Bruyne and Raheem Sterling joined by Ilkay Gundogan, who has more goals and assists in the Champions League than in the English top flight despite playing fewer than half as many minutes.
In the previous release of our rankings there was a surprising name at the top our our defensive list: young Liverpool right-back Trent Alexander-Arnold. He did not feature in their most recent outing though and has been supplanted by Barcelona goalkeeper Marc-Andre ter Stegen. With just two goals conceded in eight matches so far, and another clean sheet in a comfortable win over Chelsea, he looks the best remaining custodian now that David De Gea's Manchester United have been eliminated.
Liverpool have four players in the attacking top 10 and are just as well-represented in the defensive table, with Alberto Moreno tucked into third behind Alexander-Arnold and both Loris Karius and Joel Matip further down. Moreno has three assists and four clean sheets at left-back and is another player who has flourished far more in Europe than in domestic league matches, where he has found himself rotated for Andrew Robertson.
The pairing at the heart of Barcelona's impressively mean defence are uncontroversial inclusions: Gerard Pique and Samuel Umtiti are difficult to separate in the rankings, but the more regular attacking threat posed by Pique gives him the edge. He has been involved in chances in five of his seven appearances, whereas Umtiti has only done so in one fixture so far.
