Pochettino blasts 'nightmare' VAR

Tottenham manager Mauricio Pochettino branded the Video Assistant Referee (VAR) system that will be used at the World Cup this summer a 'nightmare' after his side was involved in another stop-start FA Cup tie.

Spurs cruised into the semifinals with a 3-0 win at Swansea with Christian Eriksen scoring twice to make light of Harry Kane's absence through injury.

But that didn't prevent Pochettino from criticizing the use of technology as a lengthy delay followed a decision to rule out a Son Heung-Min strike for offside with Spurs leading 1-0.

"It's a nightmare. I feel so sorry for the people trying to use that system," said Pochettino.

"I think I prefer it when the ref and assistant make mistakes than to wait three or four minutes for things."

Spurs have had to cope with more VAR controversy than most sides in England as their 6-1 fifth-round replay over Rochdale was littered with controversial video reviews.

On Friday, FIFA president Gianni Infantino gave the official green light for VAR to be used at the World Cup despite lingering doubts over its implementation.

The technology has been used widely in leading European leagues in Germany and Italy this season, but has been limited to a series of trials in cup games in England.

"We now need to see the reality of how it is going to affect the staff on the touchline and the officials," added Pochettino.

"It is so complex, but the worst thing for me is the effect for the fan. It is going to be a massive problem for the future.

"We will see what happens at the World Cup."
