Chelsea boss Jose Mourinho expects Diego Costa to be fit for their clash with Arsenal.

Mourinho initially revealed that Chelsea's top scorer will miss the rest of the month with a hamstring problem sustained against Stoke.

But Mourinho says Costa, who scored in the 2-0 win over Arsenal in October, has recovered quicker than expected.

He said: "Diego is progressing very well, I think he has a chance for the next weekend. Our target was for him to play the last four matches. Arsenal is the sixth from the end, so if he doesn't play against Arsenal or Leicester, it is not a problem because we were always focusing on the last four.

"But things are going so well he has a chance (to face Arsenal). He's training, he starts training with the rest of the squad next week."
