In one of the strangest years in football history, Leonid Slutsky has provided one of the most unexpected and bizarre moments of them all.
Rubin Kazan manager Slutsky provided the Christmas gift that not many would have thought up, as he decided to switch from the touchline to the stage delivering his rendition of a Mariah Carey classic.
The Russian Premier League side decided to get into the festive spirit, as they posted a music video of their manager singing 'All I Want for Christmas is You'.
There was no escape for the squad who also took part in the video which was posted on Youtube on Sunday.
