Lyon were the biggest climbers in our European Power Rankings this week, the new Ligue 1 leaders rising three places in our list of Europe's best clubs.
OL beat Troyes 2-1 to go two points clear at the top of French table and jump to 16th in our elite rankings with a net gain of 18 points.
Bayer Leverkusen - one of five teams from Germany, Russia and Ukraine in our table still on a winter break - drop a place as a result.
Tottenham fall two places after their goalless draw at home to QPR but otherwise there is no change to the remainder of the table.
That said, Manchester City continue their rise, even though they do not improve on their position this week. Roberto Mancini's side remain in sixth, but with 38 points gained following their Premier League win over Arsenal, they are closing in on fifth-placed Borussia Dortmund.
While City were the biggest winners in terms of points this week, the Gunners were the biggest losers. That defeat to City sees Arsene Wenger's team drop 39 points, although they stay in 14th.
Barcelona, at the top of the table, increase the lead over second-placed Real Madrid after the Catalans continued their march towards another Liga title with victory at Malaga, while Madrid slipped up in a goalless draw with Osasuna.
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.
