Despite a busy New Year period in some leagues across the continent, there is little change in the first of our European Power Rankings of 2013.
Barcelona remain on top, ahead of Liga rivals Real Madrid, with Manchester United and Bundesliga duo Bayern Munich and Borussia Dortmund in behind.
Manchester City stay in sixth, although Roberto Mancini's side are 16 points better off after some high-scoring festive victories - 4-3 and 3-0 over Norwich and Stoke respectively - in the Premier League.
Chelsea and Juventus were the biggest losers in terms of points since Christmas, both the European champions and the Italian giants losing 54 points. Chelsea, though, manage to hold on to ninth place, while the Old Lady drop to 11th.
Valencia and Arsenal swap places in 13th and 14th while the Gunners' North London rivals Tottenham jump up to 17th.
The winter break in Germany means no Bundesliga sides added - or lost - points this week. The same goes for Russian and Ukranian clubs.
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.
