Wenger commends Wilshere's 'mentality'

Arsenal manager Arsene Wenger praises Jack Wilshere's mentality as he makes his return to training after a 14-month absence through injury.

The midfielder injured his ankle in a pre-season friendly in August 2011 and subsequently missed the whole of the season.

Wenger also says his team are "very ambitious" and expects tough test against the champions Manchester City at the Etihad on Sunday.
