Virgil van Dijk may reportedly face 7-8 months out after suffering an ACL injury.
The Reds defender was on the receiving end of a horror challenge by Everton goalkeeper Jordan Pickford in the first half of the Merseyside derby match.
He had to be replaced by Joe Gomez and was seen limping off the pitch.
According to beIN Sports presenter Richard Keys, the defender has done his anterior cruciate ligament in that incident with Jordan Pickford and Liverpool will be without him for the best part of six/seven months.
Pickford was lucky to escape a red card and Liverpool have asked the Premier League to review the potential red-card by the Everton No.1 goalkeeper.
“It was a clear penalty I saw and then we saw the flag went up. I thought they would still look at the foul but that didn’t happen,” Klopp said, as per BBC.
“I don’t want to say Jordan Pickford wanted to do it but it is not a challenge how a goalie can do in the box.
“Virgil played I don’t know how many games in a row, he plays with pain, but he couldn’t play on and that’s not good.”
