Rio Ferdinand says United's defensive solidarity is down to consistent selection of a settled back four.
The Reds have earned 25 clean sheets from 45 matches in all competitions so far this season. And it's no coincidence that Wes Brown, Ferdinand, Nemanja Vidic and Patrice Evra have started 22 games as a complete unit.
"I said when I first signed for United that when we got a settled back four we would see the benefits as individuals and collectively. That's what we're seeing at the moment."
United's defence once again proved impassable against Liverpool on Sunday, and Ferdinand and Vidic in particular were outstanding. The pair silenced Fernando Torres, who arrived at Old Trafford having scored nine goals in six games.
It was the continuation of one of the most formidable central defensive alliances in the Premier League, and Ferdinand says their understanding happened completely naturally.
"It takes time to get used to playing alongside some players, but myself and Vida hit it off quite quickly. Our styles just gelled, it's as simple as that," he told MUTV. "There are some players that happens with, and long may it continue."
..rio and vida..really a match made in heaven ...
