Arsène Wenger has revealed the latest team news ahead of Sunday's Premier League match against Chelsea:

on the latest updates…
Compared to last week we have no big problems from the squad that was available to face Stoke. The good news is that Ozil will certainly be available. For Alexis the next few days will be decisive but I think this time he will make it to be available for selection.

on Alexis
The doubt is that he has been out for a long time and [there is] the risk of a setback if you try to go too early. To be clear on all the tests is one thing, after he is clear on training is another thing, and after that the intensity of a big game which you can never repeat in a training session. You can make sure after a certain amount of time that the risk is minimal. I am cautious with him because we cannot afford a setback with him. A setback would mean a very long period out so we don’t want to take this gamble. The signs he has shown in training this week are positive.

on Coquelin, Welbeck and Rosicky…
Coquelin is back in full training today and he is ahead of schedule. He has still a few steps to go through. Welbeck will be in full training next week so that is positive news. It is possible Rosicky will play in the under-21 game [on Friday]. He was a bit sick at the beginning of the week but we planned for him to play tomorrow night. We have a few players coming back because we go into a very important period now for us.
