Bayer Leverkusen rocketed up the European Power Rankings this week as the Bundesliga side made it three German clubs in the top 17 of the continent's finest teams.
Andrea Schuerrle kick-started things against Schalke - second only to the marauding Bayern Munich in the Bundesliga - before Stefan Kiessling completed a 2-0 win to catapult Sami Hyypia's men into 17th place in our list, with 28 points gained over the past seven days.
Flip-flopping places with Leverkusen were the Zlatan Ibrahimovic-less Paris-St Germain, the French capital club's 2-1 home defeat to Rennes seeing them drop to the foot of our standings.
In the only change to the top 10 this week, Chelsea fell a place to ninth after defeat at West Brom saw Atletico Madrid, who won at Granada, leapfrog the London club.
Chelsea's drop in points - 43 - was bettered only by PSG (51) and Manchester United, whose shock defeat at Norwich meant they lost 54 points, although Alex Ferguson's side remain in third in our rankings, given their sizeable advantage over Bayern in fourth.
At the top, Spanish giants Barcelona and Real Madrid stay out in front thanks to routine victories in La Liga over the weekend while Manchester City and another German club, Borussia Dortmund, complete the top six.
Arsenal's North London derby thumping of Tottenham means the Gunners jump a place ahead of Juventus in 11th while further down the table Lyon and Inter also swap places in 18th and 19th.
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.
