Mauricio Pochettino is likely to face an FA investigation over his conduct following Spurs’ 2-1 loss to Burnley after confronting referee Mike Dean.
Pochettino’s men suffered a seventh Premier League defeat of the season to all but end their title hopes.
Harry Kane had equalised after Chris Wood’s opener, only for Ashley Barnes to turn home with seven minutes remaining, handing Sean Dyche’s resurgent side all three points.
The result leaves Spurs five points behind both Liverpool and Manchester City ahead of the Reds’ trip to Manchester United on Sunday.
The flashpoint occurred at full-time as Pochettino and his staff made their way onto the field.
Pochettino fronted up to Dean and words were initially exchanged.
Dean asked an unhappy Pochettino “what’s your problem?”
The Spurs chief responded “you know what”, to Dean, before appearing to walk away, hinting at his displeasure with the corner awarded that led to Burnley’s first goal.
However, something was said during that moment, at which point Pochettino and his irate assistant, Jesus Perez, returned and got in the face of the official and one of his assistants.
“What, what what? What did you say?” shoulted an unhappy Pochettino, while Perez vehemently jabbed his finger towards the face of Dean, who could be seen telling the Spurs boss to “go away”.
Realising a Sky Sports camera was close in the vicinity, Pochettino then pointed the assistant official in the direction of the camera and suggested he repeat his statement in front of it.
Pochettino continued to vent his anger, within a few inches of his face, before being pulled away from Dean by Burnley defender Phil Bardsley.
Speaking after the game, Pochettino swerved the incident, but stated his belief that Spurs’ title chances are over after the loss.
“Of course we made a few mistakes – we don’t deserve the defeat, but that is football.
“I think it’s so important to understand a game that for us was so important. I believe it’s going to be decisive.
“But I think the emotions, everyone was nervous, some time we find answers and try to justify the defeat.”
