At the end of the game, both Pochettino and his assistant Jesus Perez confronted Dean on the pitch and both had to be held back as they remonstrated with the referee.

He added: "It's not how I normally behave, maybe because I knew very well before and after the game, when we lost, that it is going to be hard to be a real contender".

Pochettino complained bitterly to the fourth official, but the Argentine's protests were quelled as Tottenham grabbed a controversial goal of their own eight minutes later. Maybe we are heroes if we win at Stamford Bridge and beat Arsenal, but it's the same feeling as when we lost against Watford.

Asked if he would apologise to Dean, Pochettino added: "Yes, maybe, good point".
Spurs' shock defeat kept them on 60 points, still five adrift of leaders City and Liverpool, who have the chance to move three points clear at the top when they visit Manchester United on Sunday.

"Never was the game you can say was under control".
Christian Eriksen saw a shot saved and then lofted a perfectly weighted pass to pick out Kane's run into the area, only for the forward to show too much of the ball to Tom Heaton.
