Jose Mourinho has dismissed claims his Manchester United players were in the wrong during the chaotic post-match confrontation that overshadowed Sunday's Manchester derby at Old Trafford.
England's Football Association is investigating claims around 15 people were involved in a physical altercation after Mourinho complained about the volume of Manchester City's dressing-room celebrations.
Mourinho had a carton of milk thrown at him before a melee ensued involving players and staff in which City coach Mikel Arteta was left with a cut below his eye after being hit by a plastic bottle.
Asked about reports the bottle that hit Arteta was thrown by United striker Romelu Lukaku, Mourinho said: "Accuse? Prove? Show evidence and punish him."
Some City staff have claimed one of their physiotherapists was punched during the ruck, which took place in a corridor leading away from the tunnel, but United have denied their players threw punches.
Mourinho said he was certain his players had not done anything untoward.
"I know," said the United manager. "I am not confident: I know."
When a reporter asked Mourinho if he feared punishment over the brawl, he responded: "I think you work for another club and not for the press."
The FA has given both clubs until 6pm local time (1800 GMT) on Wednesday to offer their accounts of what happened and will then decide whether to act.
"What we did in the Arsenal stadium, you know? It was completely diverse (different)," he said.
"What we did, what happened after that match, the way we behaved as winners."
United host Bournemouth on Wednesday, when they will begin the task of trying to chip away at City's huge 11-point lead in the Premier League.
Speaking to newspaper reporters at United's Carrington training ground on Tuesday, Mourinho became visibly agitated by repeated questioning about the City brawl.
At the end of the briefing, as he left the room, he berated journalists for not asking him more questions about Bournemouth.
"You don't like Bournemouth, hey?" he asked.
"You don't respect them? You don't think they are a team capable of coming to Old Trafford and doing well? No respect for (Bournemouth manager) Eddie Howe? No respect for the players?"
