Liverpool legend Jamie Carragher has slammed Martin Skrtel and Mamadou Sakho as being 'mentally weak' after their 3-3 draw with Crystal Palace on Monday evening.
The Reds took a first-half lead through Joe Allen before Daniel Sturridge and Luis Suarez scored after the break to put the Reds in a commanding position.
However, the home side struck three times in the last 12 minutes, and Carragher blamed the defensive partnership for allowing the Eagles to snatch a result that leaves the Reds' title challenge hanging by a thread.
He told Sky Sports News: "I look at those centre-backs and that's weak mentally for me, not pushing out.
"You do that as a centre-back. In plenty of tough away games you keep driving out and then you've got to come back and then you've got to keep pushing out.
"That's 17 games Sakho and Skrtel have played together now and one clean sheet. They always concede goals whenever they play together."
The result took the Reds to the top of the Premier League, but means that Manchester City need four points from their final two games to be crowned champions.
