Jack Wilshere has resumed full training with the Arsenal first-team squad.

The 20-year-old England international missed the whole of last season with a foot injury, but returned to full training on Thursday for the first time in more than a year.

Arsène Wenger was asked about Wilshere at Friday's pre-match press conference. This is what the manager said:

on Wilshere's attitude…
He had ups and downs and many downs because he had a few setbacks. He dealt with it very well, especially in the last three months. He was highly focused every day, he was in every day very early and worked all day through. He is rewarded now with a good condition. We have to be a bit cautious, because when a guy has been out for 14 months it takes a while to get back to match fitness. He is fit to practice and play, but to put high-level performances in takes time.

on his commitment…

I have never had any doubts about that, but when you are so young and out for 14 months that is a good test for your mental strength. On that front he has been absolutely brilliant because he had not only ankle surgery, but when he thought that was over he had knee surgery. He handled that very well, I must say.

on a possible comeback date…

I cannot tell you anything about that. It will take a few weeks. We will see how well he responds in the first two games. He has to play games in the reserve [Under-21] team and see how well he comes out of that. I have to look at the schedule, I first want to give him 10 days training before he plays his first game.

on Wilshere's first training session…
It went well, and we will see how he responds to the training now. We will have to be a bit patient and monitor him well. He needs a few games, he has not played for 14 months and needs games in the reserves.

on whether he was concerned over Wilshere's recovery…

I refuse to give up, because he’s a 19-year-old boy, so I always thought he would come back. I’m not medically expert enough to know how big the damage was in his ankle. [Wilshere not coming back] never crossed my mind. Has it crossed his mind? Only he can answer that – I think yes. He’s mentally a strong boy, he’s always had a good level of confidence. I believe what he has gone through will make him even stronger.

on Wilshere's fight for a first-team place...

The biggest battle for him is just to enjoy every day now. For the rest I don't worry too much for him.
