Manchester United hero Rio Ferdinand took aim at Victor Lindelof after their 1-1 draw at Southampton.
Daniel James put United in front with a thunderous strike in the first half, but the hosts levelled in the second period through Jannik Vestergaard's header.
"If you look at the two centre halves for the goal, they know where the danger is, they're both pointing," Ferdinand said on BT Sport.
"They should shuffle against the danger man. They're both passing the buck there. A Sol Campbell or Martin Keown would be looking for the danger man and taking responsibility.
"Lindelof is the main culprit here. It's a case of personal pride. They both have to say 'have I done enough there?' If Lindelof gets tight earlier on, Vestergaard can't get a run on him."
