Arsenal boss Mikel Arteta feels Kai Havertz is up for today's clash at Chelsea.
It will mark Havertz's return to his old club for the first time since joining from the Blues.
Arteta said: The last touch of the game that he had and the contribution he had against City was terrific.
It was difficult to make the decision whether or not to play him but as well we knew that the last 25-30 minutes against City were going to be critical.
And the impact that the subs had was crucial to the result and I'm really happy how he reacted and contributed to the team.
Could it prove to be a big moment for him? I hope so, I hope so, and I can see that the confidence is shifting and he's in a much better place.
And we have to continue to do that and he needs to play."
