Wilshere says he is approaching full fitness.
"I have got better every game. [I'm] maybe 90%," Wilshere said. "I'm not sure. Every game that goes by I feel better and better fitness-wise.
"When I get up to 100% I will really show what I can do.
"It's a new experience for, my first injury," he added. "I didn't know what to expect.
"I spoke to a few players who have had long-term injuries. They said you will come back and have a good game and you think 'I am back,' then you will have another game and you are not so good.
"I think the first few games my adrenalin got me through which is why I was so up for it. Then you start to realise it is not as simple as that and things start catching up with you. Then you start to get back to your best."
