Fulham striker Aleksandar Mitrovic is facing a lengthy ban after the Football Association said its standard punishment for his sending off at Manchester United was “clearly insufficient”.

The Serbian has been charged with violent and improper conduct after a straight red card for pushing referee Chris Kavanagh during Sunday’s 3-1 FA Cup quarter-final defeat.

Manager Marco Silva has also been charged with abusive behaviour towards match officials, and will also face an improper conduct charge for allegedly throwing a water bottle in the direction of the assistant referee.
