Tottenham boss Jose Mourinho condemned Eric Dier following his altercation with a supporter in the stands after Spurs’ FA Cup exit to Norwich City.

In the aftermath of Wednesday's penalty shoot-out defeat to the Canaries, Dier climbed into the lower tier of the West Stand and confronted a fan, who is alleged to have been arguing with his brother.

Dier could face a Football Association investigation after footage of the incident went viral on social media.

"I think Eric Dier did something that we professionals cannot do but in these circumstances every one of us would do," said Mourinho.

"Because when somebody insults you, and your family is there, and you get involved with the person that is insulting you, in this case a younger brother, I think Eric did what we professionals cannot do.

"But I repeat, probably everyone of us would do. I repeat, we professionals we cannot do, but I repeat I am with the player and I understand the player.

"This person insulted Eric, his family was there. The young brother was not happy with the situation and then Eric, I repeat (he) did what we professionals cannot do, but did something that probably we would do."

The incident happened in the area behind the dugouts, which is a corporate section, and Mourinho criticised it for not housing 'real Tottenham fans'.

"The people that are in these privileged positions by the tunnel," he said.

"Of course some are Tottenham fans but I think a lot of corporate, a lot of invitation, a lot of people with special status and probably it's the place of the stadium where I sometimes have doubts over if they are the real Tottenham fans because these are the ones who support the boys until the last."
