Emmanuel Adebayor's hot streak has helped Arsenal back to the top of the European Power Rankings.

We take into account both domestic and European performances, plus the relative difficulty of each team's league, to find out who is the best team in Europe.

It has been nip and tuck between the top three all season, and this week sees Arsenal return to the summit courtesy of their win at Manchester City, while Manchester United were held at Tottenham Hotspur.

United drop to third behind Internazionale in a race that promises to go right to the wire.

Further down the table Europe's sleeping giants are beginning to wake up, with Bayern Munich and Milan rising three places each, and Liverpool climbing two to 16th.

There are no newcomers in the top 20, with UEFA Cup holders Sevilla narrowly missing out for the second week on the trot.

See below table for how the formula works:

1 (3) Arsenal - 25.13

2 (2) Internazionale - 25.12

3 (1) Manchester United - 24.93

4 (4) Barcelona - 22.35

5 (5) Real Madrid - 21.21

6 (6) Chelsea - 20.80

7 (8) Porto - 20.17

8 (7) Roma - 19.88

9 (9) Villarreal - 19.53

10 (10) Everton - 19.47

11 (12) Fenerbahce - 19.43

12 (11) Atletico Madrid - 19.30

13 (16) Bayern Munich - 19.08

14 (17) Milan - 19.08

15 (14) Panathinaikos - 19.05

16 (18) Liverpool - 18.96

17 (13) Hamburg - 18.92

18 (15) Bordeaux - 18.88

19 (20) Rangers - 18.14

20 (19) Olympiacos - 17.80

HOW IT WORKS

We take into account a combination of both domestic and Champions League performances, factoring in the relative difficulty of each team's league, to find out who is the best team in Europe.

Scores are based on points per game in domestic league and European games.

Domestic points per game are multiplied by the league coefficient - either 4, 4.5 or 5 - with teams in stronger leagues getting more credit.

Champions League victories are counted as three points for a win and multiplied by a coefficient of 5.

UEFA Cup victories are counted as three points for a win and mulitplied by a coefficient of 4.

Domestic and European totals are then added together. If a side has played in both Champions League and UEFA Cup, its European total is an average of the two scores.

League coefficients:

England, Spain, Italy = 5

Germany, Portugal, France = 4.5

Others = 4

Example: Arsenal

60 points from 25 Premier League games = 2.40 points per game.

Multiplied by league coefficient of five - 2.40 x 5 = 12.00

21 points from 8 Champions League games (including qualifying) = 2.63 points per game.

Multiplied by European coefficient of five - 13.13

Total score = 12.00 + 13.13 = 25.13
