Manchester United defender Rio Ferdinand insists they can be relied upon being stronger at the back.

The Red Devils picked up an important three points as they beat Liverpool 2-1 at Old Trafford to retain their seven-point lead at the top of the Premier League.

"I think we've got players who the manager can put 100% faith in to come in and do jobs," he said.

"Jonny Evans has done fantastically well when Vidic has been out. Chris Smalling has done well when he has come in and so has Phil Jones.

"We've got players who we know that the manager can be confident about putting in and I think that's more important than anyone one of us as individuals."
