Liverpool manager Jurgen Klopp wants to see an improvement in VAR.
The technology has become one of the most divisive issues in football, with many calls subject to huge debate.
And Klopp says VAR must be improved to maintain the integrity of the game.
"In this moment it's more how we use VAR. The clear and obvious error, that's not right because what is a clear and obvious error? It's right or wrong," the manager said in an interview with This is Anfield when asked what one rule he would change in football.
"Yeah, the ref could see it maybe like this…
"And it's not about us, it's in general. We now have a situation, there's a foul and then the ref says play on and then you see, the whole world is clear, no, it was a foul.
"The clear and obvious and the understanding I would change it immediately. The one in the office says, 'No, it was a foul' bam, foul and go back for the free kick or a penalty, whatever, just for that and it would make things so much easier.
"Now we have everyone thinks it was a mistake by the ref, which isn't a problem, it happens as the game is so quick, but you have another guy in the office who sees it better and now he says, 'Nah, I don't want to overrule him.'
"Where's the problem? It's all about the right decision, nothing else. So to delete this little phrase, clear and obvious error."
