Manchester City full-back Aleksander Kolarov has poked fun at his apparent steely persona by taking on the club's kit man Les Chapman in a boxing bout.
The Serbian, who got his reputation last year following a less-than-enthusiastic rendition of 'Jingle Bells', remained silent throughout the whole video, which is part of City's digital advent calendar.
Chapman, who was coached by Edin Dzeko in the tongue-in-cheek piece, was beaten by a single punch from Kolarov, who marks his victory by saying: "If he dies, he dies."
Watch the pair's bout below:
