Jose Mourinho may have sidestepped the issue on Wednesday, but it is understood that he is watching the outcome of Arsene Wenger's misconduct charge with considerable interest.
Wenger has until 6pm on Thursday to respond to the charge after he was sent to the stands by referee Jon Moss in Arsenal's win over Burnley on Sunday, then pushed fourth official Anthony Taylor in the tunnel.
Publicly, Mourinho did not want to be drawn on the incident, saying only: 'I never pushed the referee so I don't have a comparison. I have no idea.'
Privately, however, it is believed that the Manchester United manager will indeed draw comparisons between any punishment meted out to Wenger and his own brushes with match officials in the past.
