Liverpool legend, Jamie Carragher has singled out Manchester United midfielder, Casemiro and claimed he put in his worst performance so far during their 7-0 defeat at Anfield on Sunday.
The Reds were only 1-0 up at half time, but went ahead to put six past their rivals after the break.
It was the joint-heaviest defeat for United in a competitive fixture.
Casemiro has been impressive for the Red Devils since he arrived from Real Madrid in the summer.
But Carragher was full of criticism for the Brazilian on Monday Night Football.
He said: “Casemiro has been one of the best players in the league this season, but he was very very poor on Sunday.
“You could see he wasn’t at the races. A player of his class shouldn’t give the ball away the way he did. He was supposed to look after Harvey Elliott, but he made it too easy for him. The second goal is the killer for United. Casemiro couldn’t get near anyone, he’s fallen over twice.
“It was his worst game for passing, he didn’t win one tackle.”
