Marouane Fellaini has been warned about his future conduct by the FA after failing to leave the pitch quickly enough following his sending-off in the Manchester derby.
Fellaini will serve a three-match ban for his offence at the Etihad on Thursday night, missing the Premier League games against Swansea, Arsenal and Tottenham.
The big Belgian midfielder became embroiled in a confrontation with Manchester City players after he was shown a straight red card by referee Martin Atkinson in the 84th minute of the goalless draw.
The FA have acted in the past to punish players who fail to leave the pitch, notably when Emmanuel Adebayor was handed an additional one-match ban and fined £7,500 in 2007 for ‘reacting aggressively and failing to leave the field of play immediately’ after he was sent off playing for Arsenal against Chelsea.
