Alisson Becker’s howler allowed Tottenham to earn a share of the spoils with 10-man Liverpool, with talking points aplenty after a gripping contest in north London.
Liverpool were 2-1 up after Diogo Jota and Andy Robertson goals cancelled out Harry Kane’s early strike – his first in the league since October – and heading for the three points until Alisson failed to connect with a clearance and Son Heung-min rolled home into an empty net.
Robertson was then sent off for a wild kick on Emerson Royal after VAR upgraded his yellow card, but there was controversy in the first half when referee Paul Tierney did not even look again at Kane’s studs-showing tackle on the Scot.
Liverpool also felt they should have had a penalty in the first half after Jota appeared to be bundled over, while Spurs felt Dele Alli was fouled in the box prior to Robertson scoring.
In the end a draw was a fair result, but Klopp was fuming with referee Tierney over the decisions that went against his team and he was convinced Kane should have been sent off for a wild first half challenge on Robertson.
"I think we all agree it is a clear red card, I just need to ask two people, Mr Tierney and whoever was the VAR," Klopp fumed.
"You can give Robertson a red card, he knows that himself but Harry should not have been on the pitch in the second half and then tell me how the game goes. If Mr Tierney does not see it I get that. But the VAR was obviously awake because he told him to look again at Robertson.
"With the penalty he tells me he stopped on purpose because he wanted to be hit. The referee had the best position in the whole stadium."
Klopp was picked up telling Tierney he is "the only referee he has a problem with" as former Reds defender Jamie Carragher admitted his comments may have gone too far.
"You cannot condone speaking to a referee but managers are emotional," he told Sky Sports. "We want managers to be honest and emotional and the decisions that go against Liverpool, it was a blatant penalty, Harry Kane should have been sent off.
"We were frustrated with VAR a year or two ago, we are OK with it at the moment but we have gone right the other way. Last season a touch on the ankle was a decision but now we are thinking what is the point of VAR with penalties? We saw that with Newcastle, it is not VAR, it is who controls it. Chris Kavanagh is VAR and that has to be a penalty.
"It might have happened 100 miles an hour but the whole point of VAR is to help the referee. This is the whole point of bringing VAR in. The clear and obvious is a real problem because they don't want to re-referee games. VAR helps referees on big situations and that was a big one."
"You don’t need a ref that helps you. You need a ref who is clear and objective. In three decisive decisions he was once right and that was with Robbo, and twice wrong. All three were against us."
Football Association chiefs may now consider whether Klopp's comments have crossed the line as even though all the key decisions in the game went against his team, Tierney will now be under the spotlight the next time he takes charge of a Liverpool game.
