After last night's match against Norwich City, Eric Dier climbed over rows of seats to confront a fan, who had allegedly been involved in an altercation with the player's brother.
It was a physical confrontation and immediately it happened, news spread around social media that it was because the fan had racially abused Gedson Fernandes after his penalty miss, but now his manager Jose Mourinho has come out to say it was because the fan in question insulted Dier's brother.
"When someone insults you and your family is there and your family gets involved with somebody who is insulting you, in this case, a younger brother, I think Eric did what we professionals cannot do but, I repeat, probably every one of us would do," said Mourinho.
Asked if the club would take any action against Dier, Mourinho added: "If the club does that I will not agree, but he did wrong."

Dier scored his penalty in the shootout, but Erik Lamela, Troy Parrott, and Gedson Fernandes missed from the spot to condemn Spurs to a fourth straight defeat in all competitions.
