Wilshere has failed to find a new club after leaving Bournemouth at the end of the Championship season, with former Arsenal team-mate Arteta handing him a chance to maintain his fitness
Once considered the rising star of the English game, Wilshere has been battered by a succession of injuries over the course of his career.
Those injury issues mean that clubs have not been keen to offer the midfielder a contract, despite the fact he is currently a free agent after leaving the Cherries at the end of last season.
With Wilshere still struggling to find a club more than a month after the summer transfer window ended, Arsenal boss Mikel Arteta has now invited him back to the club to maintain his fitness.
