Everton boss Frank Lampard said Liverpool's Virgil van Dijk should have been sent off during the sides' 0-0 draw following the defender's studs-up challenge on Amadou Onana at Goodison Park.
Van Dijk was shown a yellow card by referee Anthony Taylor after the 76th-minute foul on Onana in which the Netherlands centre-back missed the ball and caught the Everton midfielder on the shin with his studs.
VAR did not take further action after Taylor booked Van Dijk, but Lampard said the referee should have been told to review his decision by Video Assistant Referee Darren England, with television replays clearly showing the full extent of the challenge.
"I love Virgil van Dijk, as a player he is fantastic," Lampard said. "But sometimes you mistime tackles, it was up on Amadou's shin and his foot was on the ground.
