Former English Premier League referee Mike Dean says a technical glitch was responsible for VAR failing to intervene and deny Cristiano Ronaldo a penalty against Ghana.
Referee Ismail Elfath pointed to the spot in the 63rd minute after Ronaldo was fouled by Ghana's Mohammed Salisu.
Replays suggested the 37-year-old was already heading towards the turf before he, himself, initiated contact with the Salisu.
"It’s scary, it is scary,’ Dean, now a dedicated VAR following his decision to retire from refereeing at the end of last season", Mike Dean told beIN Sport.
"I’m just astounded and I like to back referees all the time and you can’t support stuff like that. You can’t defend the indefensible. He should have gone to the screen, he should have looked at that.
"The only thing I can think that may well have happened for some reason, and it does happen sometimes in the UK, there’s angles in the VAR hub that they don’t get straight away.
"The VAR doesn’t choose the angles the operator next to him does. If he can’t get that angle there might be some kind of technical glitch. I just cant’ understand why he wasn’t sent to the screen. It’s 100% wrong."
The defeat means Black Stars are bottom of Group H after Uruguay and South Korea played out a goalless draw earlier on Thursday.
The Black Stars will now switch their attention to their attention to the match against South Korea on Monday before taking on Uruguay on December 2 at the Education City stadium.
