In his regular BBC Sport column, Robbie Savage looks at Arsenal's top-of-the-table clash with Chelsea on Sunday and explains why Arsene Wenger might finally get the better of Jose Mourinho, at the 13th attempt.

Arsenal manager Arsene Wenger has got an abysmal record against Jose Mourinho but there are a few reasons why I think he will finally end his hoodoo against the Chelsea boss this weekend.
Form, confidence, style of play and - crucially - their new defensive discipline can all help Arsenal beat the Blues at Emirates Stadium.
The Gunners will still have to work exceptionally hard to make it happen, though, because defeat in a big game is just not something Mourinho experiences very often.

Old rivals: Arsene Wenger and Jose Mourinho's first meeting was a 2-2 draw at Highbury in December 2004
Since the start of his first spell as Chelsea boss in 2004, Mourinho has played 39 league games against his main rivals in England - the Gunners, Liverpool, Manchester United and Manchester City - and lost only three of them.
Mourinho's results against the Gunners have been particularly impressive. In 12 meetings in all competitions over the past decade, Wenger has never beaten him.

If you think about the type of football both teams have produced in the last few years under Wenger and Mourinho, you can understand why.
In the past, the way Arsenal have played has suited Mourinho and Chelsea down to the ground because the Gunners have been cavalier going forward and left themselves wide open at the back.
Do that against Mourinho, who likes to get men behind the ball and be ready to pounce on the break, and he will eat you alive.
Mourinho's approach won't change this weekend - the question is how well Arsenal can deal with it this time.

'Arsenal will be doing most of the attacking'

Sunday's game will probably be very similar to the way things went in Chelsea's win over Manchester United last weekend, at least in terms of the pattern of play.
Like United, Arsenal will probably see more of the ball and be the team doing most of the attacking. Chelsea will be defending deep and in numbers.
United's problem was that they still failed to really break Chelsea down and ended up having a lot of long shots.

But Arsenal can look to do things differently with their possession because of the quality and type of forward players they have got.
When they find some space between Chelsea's midfield and defence they will keep on passing and probing until they get behind them, rather than shooting from distance.
You often hear Arsenal get accused of trying to pass the ball into the net. Well, that patient approach will work perfectly against Chelsea.
If they play that extra pass, as many times as it takes, I think they will end up wearing Chelsea out.
