Manchester United and Manchester City fans have been given the opportunity to get rid of any unwanted Carlos Tevez shirts before Sunday's derby at Old Trafford.
Fans have been encouraged to bring along their shirts to be exchanged for new ones. All donated shirts will be given to local charities or sent to Argentina.
The majority of United fans have not forgiven Tevez for joining their local rivals, while City fans are still smarting over his alleged refusal to play for the club last month.
The striker moved from United to City in 2009 for an undisclosed fee.
