Wenger believes hungry Jack Wilshere can recapture best

The 25-year-old is in line to face Cologne as the Gunners begin their Europa League campaign at home tonight — 383 days since he last wore an Arsenal shirt in the win at Watford last season.
Wilshere has struggled with injuries in recent years and spent most of last season on loan at Bournemouth in an effort to prove his fitness and ability to Wenger.
