Man city defender Kolarov played his part in the defensive effort as Man City survived to claim victory against Man U but in doing so the Serbian international finished the game minus one of his two front teeth.
Goalkeeper Willy Caballero took to Instagram after the game, sharing an image of him alongside a toothless Kolarov as the City players celebrated at Old Trafford.
Caballero captioned the image: 'Amazing game 2-1 against United at Old Trafford. In this picture with one of my warriors. Can you find the only thing He lost today.'
