Tottenham manager, Mauricio Pochettino says he feels sorry for officials who have to make use of VAR, after the system marred the 6-1 win over Rochdale.
Llorente scored a hat trick against the League One side, but VAR took center stage as it was used in the FA Cup for the first time.
Lamela had his opening goal disallowed by the system, before Tottenham were awarded a penalty, which was later disallowed following Son’s staggered run, by the technology.
Pochettino feels sorry for officials who have to deal with VAR, and believes the supporters need an explanation.
“It was a game we can talk about different things,” Pochettino told BBC Sport. “It was so complicated because of the new system, it was difficult to keep focus on the game. The job is done and we are happy because we are in a quarter-final.
“I told the players to keep focused at half-time. The circumstances were difficult. I think we have the best referees in Europe or the world but I don’t know if this system will help them or cause more confusion.
“It is a game of emotion. If we are going to kill this emotion I think we are going to change the game.
“It’s difficult for the referee – I feel so sorry for the referee and more I feel sorry for the fans because it’s so difficult to understand the situation.
“We have a tough game at Swansea and we will have a competitive time.”
