The winner and the loser.

Jose Mourinho has confirmed Chelsea will be without former Arsenal defender Ashley Cole, who is continuing his recovery from a knee ligament injury.

Midfielders Ramires and Willian are suspended as a result of their dismissals at Aston Villa last weekend.
Arsenal boss Arsene Wenger has just one new concern, with Czech midfielder Tomas Rosicky to face a fitness test.
The Gunners have long-term absentees in Aaron Ramsey, Jack Wilshere, Theo Walcott and Abou Diaby.

MATCH PREVIEW

A thousand games; no mean achievement for Arsene Wenger. Whether Wenger would choose to reach such a landmark at Chelsea is debatable. It's possible that for Wenger only a surprise party at Stoke would be less appealing than a couple of hours with Jose Mourinho.
Mourinho can be funny, charming, generous in his praise, clever and beguiling; but so often on the subject of Wenger he is ungracious and even plain bitchy - variously describing the Frenchman as a 'voyeur' and a 'specialist in failure'. Neither was true, neither becoming of the Portuguese.

"One thing about Chelsea is when they lose a game, they tend to come back and win.
"Jose Mourinho has never lost a home Premier League game and I don't think it's under threat."

However, much more important than the social pleasantries of the dugout is the destination of the three points on offer at Stamford Bridge.

Wenger has failed to win any of his 10 previous meetings with Mourinho. An end to that run would have huge implications for the title race; suddenly it would be Chelsea fading and Arsenal surging.
It would end Mourinho's unbeaten home league record as Chelsea manager, now stretching over 75 games, and leave Arsenal champing at the bit for the chance to play Manchester City next weekend once they've met Swansea on Tuesday.
But should Chelsea win this game, Wenger will be realistic enough to know that Manchester City could all but knock Arsenal out of the title race in seven days time. It really is make or break.
Things have started looking up for Chelsea after the tempest of Villa Park. The midweek win over an exceptionally tame Galatasaray was just what they needed, the Champions League quarter-final draw could have been worse too.
Meantime, Mourinho was never going to pass up the chance to have another little dig at Wenger: "I admire Wenger and I admire Arsenal, a club that stands by its manager in bad moments - of which there were quite a lot."
Miaow!
