Arsène Wenger is convinced that Jack Wilshere will eventually be better than ever - but he will need time to rediscover his "burst".

The England international returned to first-team training on Thursday after missing the whole of last season through injury. Wilshere enjoyed a meteoric rise before his lay-off and Wenger believes his youth will help him get back to the top.

The manager was asked during his pre-match press conference whether Wilshere will be as good as he was during his breakthrough 2010/11 campaign. "It is not possible, it is certain," replied Wenger.

"He will be a better player because if you have this kind of injury at the age of 20 you will take off again and move forward normally. If you have the injury after the age of 25 it is different. At his age it is no problem.

"[For example] Eduardo had limitation of his ankle. Jack has no limitation of his ankle it was just a fracture. Eduardo had a rupture of his ligaments and in construction they had to tie his ankle up so once you lose your flexibility of your ankle you are, of course, not the same player. That is not the case for Jack.

"It's difficult to predict [how long he needs to find his best form]. You want people to be patient. After three months of competition for sure he would be back. It takes some while to find the little burst again."

"He will be an international player and he will have to cope. He is a very strong guy, he had a stress fracture and that happens many times to young players. Between the ages of 18 to 20, around 60 per cent of them have stress fractures."
