Laurent Koscielny has vowed to end Arsene Wenger's win-less streak against bitter rival Jose Mourinho.

Incredibly, Wenger has never tasted victory in 12 clashes with the Chelsea boss - a drought stretching back to 2004-05.

But Koscielny insists the red-hot Gunners are desperate to break that curse at the Emirates today.

Ahead of the title showdown, the French defender said: "It's been complicated for the boss - but I hope just for once he will win against Mourinho.

"It's true Mourinho likes to play the psychological game. But that works only for a time because it's on the pitch where things happen!"
