Manchester City and United fans can ditch Carlos Tevez shirts

Supporters of both Manchester City and United are being given the chance to discard their Carlos Tevez shirts ahead of Sunday's derby.

Fans will be able to dump the items of clothing in a skip outside Old Trafford in exchange for a new club shirt.

The Argentina striker left United for City in 2009 - then upset City fans by allegedly refusing to play in last month's defeat by Bayern Munich .

All unwanted shirts will be given to local charities or sent to Argentina.

United fans are still unhappy with Tevez for leaving them to join their local rivals and, with the player's future at City uncertain, a betting company has stepped in to help.
