Arsène Wenger has revealed the following team news ahead of the Chelsea game:

on Vermaelen's progress...
Vermaelen might be available to be in the squad. We'll have to assess him. He is not injured. He came off with a calf problem on Tuedsay in the Carling Cup. It was cramp because he has not played for a long time and he only had one training session. As I say he is not injured but he might be a little bit short for a game of that intensity.

on potentially having all his centre backs fit and available...
It is a good issue to have. I think we are defensively more solid than some time ago. In the last five or six games it is the most solid that we have looked. But no matter who plays, for me, they are all good players.

on injuries to Arsenal's young full backs...
Carl Jenkinson [knee] has a little chance to be available on Saturday. If not then maybe on Tuesday for him. Gibbs [stomach muscle] is not available.
