Arsene Wenger questions Juan Mata move from Chelsea to Man Utd

Arsenal boss Arsene Wenger questions the fairness of Juan Mata's prospective move from Chelsea to Manchester United at this stage of the season.

The Gunners manager says Chelsea have already faced United twice in the Premier League so won't have to face the Spaniard again this season, while others in the top flight, including Arsenal, still have to play the reigning champions.

Wenger wonders whether the timing of such deals is fair to all clubs.
