Manchester City boss Pep Guardiola was furious after seeing Aleksandar Kolarov lose a tooth in the derby win at Manchester United.
The City boss responded to Jose Mourinho's claims that Manchester United should have been awarded two second half penalties during their second-half defeat.
He said: “If you come to see me on Monday I will tell you because I will be able to see the video properly.
“I did not see it at the time. I will have to look at the video, but maybe you should look at Kolarov.
“He has no teeth – the player has no teeth."
Although Manchester City's manager highlighted the incident after the game, he refused to elaborate.
