Liverpool manager Jurgen Klopp insists he is a fan of VAR but believes the process is failing referees and therefore the teams involved.
The Reds boss said he was so surprised the review did not rule out Manchester United's first-half goal from Marcus Rashford for an earlier foul on Divock Origi that he could not even be angry.
Adam Lallana eventually scored five minutes from time in the 1-1 draw at Old Trafford but Klopp was still bemused by the advice given to official Martin Atkinson.
"I calmed everyone down because I knew immediately.
They scored the goal and Mr Atkinson immediately signalled VAR," he said.
