The Football Association has opened an investigation and contacted Eric Dier for his observations after the Tottenham player went into the stands and confronted a supporter following the FA Cup home defeat by Norwich on Wednesday.
Spurs have also begun an investigation and believe they know the identity of the fan involved. They are not considering a club punishment for Dier while they work with the FA to establish what happened. The ruling body is considering bringing a charge against the player.
The incident happened after Norwich had won on penalties. Dier jumped over the advertising hoardings and tried to reach the supporter who had become embroiled in a disagreement with Dier’s youngest sibling, Patrick.
Dier was held back by stewards and other supporters and José Mourinho said: “I think Eric Dier did something that we professionals, we cannot do, but in these circumstances, I think everyone of us will do. Because when somebody insults you and your family is there and your family gets involved with the person insulting you, in this case a younger brother, I think Eric did what we professionals we cannot do. But, I repeat, probably every one of us would do.”
