Jurgen Klopp was furious with the performance of VAR after Liverpool drew 1-1 with Manchester United on Sunday.
Divock Origi was seemingly fouled by Victor Lindelof before the ball was turned over to United, who counterattacked through Daniel James.
The Welshman then set up Marcus Rashford to score the game's opening goal with a sumptuous cross.
Adam Lallana saved Liverpool's blushes with a late equaliser, and Klopp was unhappy with the technology after the game.
"We were good enough for a point," he told BBC Sport. "We gave Man Utd an opportunity to play the way they wanted to play with five at the back etc. They were hardworking. Our orientation wasn't good enough. We felt under pressure when we weren't and could have turned inside at some opportunities.
"The first goal I think everyone can agree it was a foul but with VAR it is not a clear foul. That is the situation. We didn't lose but it was an obvious foul. There was clear contact and Divock Origi goes down.
"They carried on and counterattacked. Yes, there is contact, I'm sure they said that but it is not a 'clear foul?' That doesn't work. That's just not how it should be.
"Then we got a disallowed goal. I didn't see it back but it was probably handball but everything just seemed to go against us. We changed a little bit our formation and had these moments.
"Then we scored the goal and was in charge of the game. The stadium was silent and people probably thought Liverpool would score but we take the point and move on."
