Liverpool legend Jamie Carragher has slammed Dejan Lovren after defeat at Manchester United.

The Croatian's fluffed clearance from Wayne Rooney's low cross fell straight to Juan Mata who fed Robin van Persie to score into an open goal.

"He's cost a lot of money but he's actually made it worse," Carragher said.

"He's made more mistakes in league as a defender and he's made a mistake for the goal."
