It’s shaping up to be a really big game for both clubs as they chase a top-four finish. Neither have been in the best of form lately.

Chelsea have really struggled at home, winning just one of their last five games at Stamford Bridge in the Premier League. They were beaten by QPR and then threw away a two-goal lead against Southampton. But with the likes of Juan Mata, Eden Hazard, Frank Lampard and the newly-arrived Demba Ba in their ranks, they still pose a considerable threat.

Arsène Wenger will be hoping for a repeat of last season’s performance at Stamford Bridge. The gap between the two sides going into the game is eight points, and Wenger will be keen to ensure that it does not increase any further. He will have been happy with his team’s display against Swansea, especially after playing with 10 men for 80 minutes against Manchester City three days before.

Jack Wilshere looks back to his best now. He was fantastic against Swansea and it will be interesting to see where he lines up, because he was deployed in a more advanced role on Wednesday night and seemed to revel in it.

January hasn't exactly gone according to plan in the Premier League. Defeat to Manchester City was tempered by the fact we played most of the game with 10 men, while the draw away to Southampton was fairly disappointing.

We now have two London derbies inside four days and it's crucial we get ourselves back on track.

I thought there were really encouraging signs in the second half against Swansea; although the finishing was awry, the amount of clear-cut chances we created was a real positive. I'd hope to see more of the same against a Chelsea side that have been defensively suspect this season.

We know Chelsea are strong from an attacking point of view, so concentration and organisation at the back will be key to getting something from the game. If we're switched on and don't make silly mistakes, then I think we've got enough firepower to take advantage of a side whose form fluctuates. I'd take a point but I don't think all three is impossible either.
