Liverpool hero Jamie Carragher slammed Virgil van Dijk during defeat at Manchester United.

United won 2-1 to hand new manager Erik ten Hag his first victory in charge at a bouncing Old Trafford on Monday evening.

Reds centre back Van Dijk was at fault for the first United goal, standing still on the six-yard line as winger Jadon Sancho had far too much time and space to score - and iconic former Liverpool defender Carragher criticised the Dutch star's "intensity".

He said: "It's the only one thing I'd ever question van Dijk on as a player. If you're going through a checklist of a centre back, he's 10 out of 10 for most things. The one thing I do sometimes think is: does he lack a little bit of intensity at certain times?

"I know you never see him on the floor and that's a strength for a defender - if a defender's on the floor all the time, that's not a good sign. But now and again, when you're in the proverbial (s***), you've got to throw yourself at (the ball).

"That one there (the Sancho goal) he was literally stood there... It's one where you've got to go flying out and just throw yourself at him (Sancho).

"Slide along the floor, make yourself as big as possible. You can't just stand there! He almost made himself smaller, the way he stood. That's the one thing I sometimes think: go, be more aggressive, maybe slide in, throw yourself in front of something."
