Mick McCarthy has claimed VAR is ruining football after admitting referees used to get "95 per cent" of decisions correct anyway.
The Republic of Ireland boss was mystified after David McGoldrick, who trained with his international team-mates in Abbotstown yesterday, was denied a goal in Sheffield United's 1-1 Premier League draw at Tottenham on Saturday.
What would have been an equaliser for the Blades was ruled out by the video assistant referee because John Lundstram's toe was adjudged to have been offside after a lengthy wait, leaving more than one member of the McCarthy family perplexed.
The Republic boss said: "My view is that it's ruining it at the minute, as a spectacle.
"My son was at the Tottenham game on Saturday and he said, 'Dad, it was four minutes and they all start booing...' It was the most ridiculous decision I've seen.
"We used to complain about referees and now we complain about somebody that we can't see. I suppose that's anonymous for them, that's okay."
McCarthy acknowledged that he and assistant Terry Connor would always sit down on a Monday to review the weekend's game and often discovered the referees were right more often than not.
He said: "TC and I would always watch the games back on a Monday. Despite the fact we might have been having a whinge about the referees, Monday morning, 95 per cent, I would say, of the decisions they got right. I preferred it before, I must be honest."
