Sir Alex Ferguson is not interested in getting involved in the spat between Carlos Tevez and Gary Neville.
The former Manchester United team-mates clashed at Eastlands on Tuesday as Tevez celebrated his equalising goal in City's 2-1 Carling Cup win.
Tevez initially made a "shut it" gesture in response to pre-match comments from Neville that the Argentina star was not worth the money it would have cost United to keep him at Old Trafford last summer.
Neville responded with a one-fingered gesture of his own, which prompted further reaction from Tevez, who followed up by winning the game with a second-half header and then aimed fierce criticism at the Red Devils skipper.
In a wide-ranging attack, Tevez labelled Neville "a moron" and "a boot-licker", which has only served to add further fuel to the fire ahead of next Wednesday's semi-final second leg at Old Trafford.
Although he has never been scared of courting controversy, United manager Ferguson has this time opted to give the whole row a wide berth.
"I am not interested," he said.
"Carlos Tevez is not our player anymore and I have nothing to say about it at all.
"Players argue with each other all the time. They have a go at each other time and time again. It is not an issue for us. We move on."
Ferguson also declined to offer an opinion on Neville's behaviour, which it has now been confirmed will not attract any further action from the Football Association, claiming he had not seen what happened.
"I am not disappointed with Gary's conduct," he said, "and I didn't see his gesture."
