It was a remarkable display of sportsmanship.

With Manchester United leading their Europa League Round of 16 tie with Real Sociedad, the Red Devils were awarded a penalty when the referee felt Patrick Dorgu had been fouled in the box. Dorgu, however, disagreed and was seen gesturing to the referee that it was a not a foul.

VAR agreed and the penalty was revoked — but just how often does a player admit something that benefits the opposition?
