Manchester City manager Pep Guardiola apologised for his team's part in the mass brawl that resulted in Sergio Aguero and Fernandinho being sent off at the end of their 3-1 defeat by Chelsea - but defended both players.
Aguero was dismissed for a wild lunge on Chelsea defender David Luiz, with team-mate Fernandinho also shown a red card for clashing with Cesc Fabregas in the melee that followed.
"It is a pity the game finished like this," Guardiola said. "I don't like that and I apologise for what happened.
"I don't think Aguero's challenge is intentional. Both players were strong, that is all.
"Then Fernandinho went over to defend his team-mate because of what the opponent did to Aguero.
"When (City winger) Nolito did that against Bournemouth, it was a red card for him and a three-game ban. That is why Fernandinho went to defend his team-mate, that is all.
"I have not spoken to him about it - if it is on TV, we will see about it."
Fernandinho will be suspended for three matches and Aguero will face a four-game ban because he has already been sent off once for violent conduct this season - the retrospective red card he received for a challenge on West Ham defender Winston Reid in August.
The pair will miss games against Leicester, Watford and Arsenal and, while Fernandinho can return at Hull on 26 December, Aguero will have to wait until City's trip to Anfield to play Liverpool on New Year's Eve.
Referee Anthony Taylor had angered City's players and fans with some of his earlier decisions, including a first-half challenge by Luiz on Aguero that went unpunished.
However, Guardiola refused to blame Taylor for the defeat, his first at Etihad Stadium since he took charge of City in the summer.
"We didn't win because we missed a lot of chances, not because of the referee's decisions," the Spaniard added.
"I am proud of my team and how we played - I came here to try to play the way we played in this game.
"You have to remember who we were playing, and that we created more chances than we did in our last two games against Burnley and Crystal Palace, when we won.
"But in the boxes we are not strong enough. When the opportunities arrive, we have to score goals because when we don't it is tough mentally for the players.
"It is a problem we have had all season. It is difficult for us to score goals and we concede them very easily."
