Arsenal midfielder Jack Wilshere says his recent injury has been the toughest to take mentally.

The injury-prone England international required surgery on his leg in September and he is set to be sidelined until late 2015.

Wilshere, 23, said his latest setback had been difficult to deal with.

"I think this one was mentally the toughest to take," he told Sky Sports.

"Last season I started the season well, got injured and missed most of the season, came back towards the end, got back in the England team, had a good game with England and then I only took two weeks off in the summer because I wanted to go back early and get fit, which I did.

"Pre-season I didn't have any muscle injuries or anything like that, it was just a freak incident in training.

"It is tough but I've got good people around me, family and friends and they really help."
