Tottenham boss Mauricio Pochettino has warned that the video referee could ‘kill’ football as Spurs’ FA Cup win over Rochdale descended into chaos.

Fans jeered referee Paul Tierney’s constant first-half stoppages to use the system in a fifth-round replay made even more difficult by a blizzard at Wembley.

Pochettino said: “Football is about emotion. It is a contest of emotion and if we are going to kill emotion in football, the fans, the people who love football, are not happy about what they saw.”

Spurs ran out easy winners with a Fernando Llorente hat-trick but only after Erik Lamela’s first-half goal was disallowed on a mystifying call before Tierney ruled out a Son Heung-min penalty due to ‘illegal feinting’.

Pochettino added: ‘The first half was embarrassing. Everyone was confused and we need to respect the fans. Emotion is why you pay for the ticket, that is why you come to the game when the conditions are so bad.

“Then you (will) say “OK, I am going to watch the game through the TV and stay at home because if I cannot shout when we score because we need to wait two minutes, you cannot express yourself”.

“I am for the new technology but be careful when you change the game that we know.”
