Arsenal boss Arsene Wenger worried about Jack Wilshere burnout

Arsenal manager Arsene Wenger says Jack Wilshere will have to be carefully managed to prevent him suffering burnout.

Wenger adds that he does not want to "set any limits" on what Wilshere could achieve in his career, after the young midfielder starred for England in Wednesday's win over Brazil at Wembley.

The Gunners travel to Sunderland in the Premier League on Saturday.
