Cash-rich Paris St Germain continued their rise up the European Power Rankings by hitting eight goals in two games last week.
Superstar striker Zlatan Ibrahimovic hit three goals in the two games as improving PSG began their European campaign with a flourish and climbed to third in their domestic table after an inauspicious start to the season.
And that has seen them rise four places to 17th in our list of the top European clubs.
With the top five of Barcelona, Real Madrid, Manchester United, Bayern Munich and Manchester City remaining unchanged, Chelsea dropped below Porto into seventh after a pulsating 2-2 draw with Juventus then narrow win over Stoke.
Arsenal move up to ninth after a win at Montpellier and draw at Man City, with Atletico Madrid dropping below them despite a 3-0 win at Hapoel Tel Aviv in the Europa League then 2-1 victory at home to Vallodolid in La Liga.
Just behind PSG are Ligue 1 rivals Lyon, who knock Spurs down a spot, while just outside the top 20 Everton are up three places to 21st.
HOW IT WORKS
To determine our Power Rankings, we use the Euro Club Index, which scientifically analyses hundreds of thousands of matches from the top divisions in all European nations as well as Europa League and Champions League games.
The Index takes into account all matches played over an eight-year period but with recent results carrying more weight than older ones.
The performance of a league's teams in the Champions League and Europa League reflects the rise or fall of the sporting level in that league. So, for example, if English teams perform well in Europe, all Premier League teams receive a small bonus in their ECI score. The ranking and its predictive power are thus made even more accurate.
