Manchester City midfielder Ousmane Dabo is threatening legal action against team-mate Joey Barton following their training ground bust-up on Tuesday.
Barton and Dabo are unlikely to play for Man City together again
Dabo, 31, was left unconscious and with a bruised eye after Barton's attack.
"I went to turn around, he hit me and knocked me out. He is a despicable coward, it wasn't a fair fight," Dabo told L'Equipe. "I am disfigured.
"This is why I am in serious talks with my lawyers to see what I can do. This should not be allowed to happen."
Dabo also accused the Professional Footballers' Association of trying to help Barton but not getting in touch with him, a claim chief executive Gordon Taylor denies.
In the eyes of many I'm seen as the one who started the fight, but that is absolutely not true
"We've been in touch with Manchester City and have been trying to make contact with both players," said Taylor.
"As regards Dabo, [PFA executive] Richard Jobson is looking to make contact with him because he deals with his brother Moussa at Oldham on a regular basis."
Dabo had to be taken to hospital after Tuesday's incident, which has led to City banning Barton until the end of the season.
But boss Stuart Pearce says the matter will not affect the club ahead of the Manchester derby against United on Saturday.
"There will be no negative response," said Pearce. "The way the squad have handled everything has been a credit to themselves. I am sure they are galvanised by it.
"The matter is now the subject of an internal disciplinary hearing.
"The board will be involved, as will myself, and we will deal with it after the season ends."
Barton's agent Willie McKay said on Wednesday that he had been banned by City because he was "an easy target" and that he was acting "in self-defence".
McKay also suggested he was Dabo's agent, a claim the Frenchman was quick to deny.
"Let's get one thing clear," added Dabo in the Daily Telegraph. "McKay has never been my agent. He only assisted my real agent with my transfer last summer.
"Secondly, he should have checked his facts before saying I was the aggressor.
"He has actually called me since to apologise for getting the story wrong, but it's too late because in the eyes of many I'm seen as the one who started the fight.
"But that's absolutely not true and that is why I'm so keen to get my side of the story across."
