Manchester United are considering banning their fans from the Champions League semi-finals - if they face a trip to AC Milan.

After the horror clashes in Rome last week that marred United's game against Roma, United may implement their own temporary ban on supporters travelling abroad if they return to Italy.

A United insider said: "In no way do we blame our fans for the problems they encountered in Italy, but for their own safety we would have to consider the possibility of refusing an allocation of tickets should we face Milan."
