Arsène Wenger revealed the latest team news ahead of the Chelsea game:

on Thomas Vermaelen...
We had good news about Vermaelen in the game against Bolton the other night. It was just cramp [that forced him to come off] so that's good news. He will certainly be in the squad at Chelsea. I don’t know yet whether he will start, I have to think about that. I feel physically he is not completely ready because he had problems to finish the game against Bolton, but he is close. We play two games in three days and I will have to evaluate the whole situation. But Thomas always wants to play.

on Carl Jenkinson...
I will know more [about Jenkinson's fitness] after training on Friday. Jenkinson was alright yesterday, but I don't know if I will take him or not. It depends how well he does in training today.
