The success of Manchester United pair Wes Brown and Jonny Evans at Chelsea has heaped pressure on established duo Rio Ferdinand and Nemanja Vidic.

That's the opinion of former United defender Kevin Moran, who says the turnaround is good for the Reds.

"The Rio-Nemanja duo looked a long-term thing. But all of a sudden it is no longer nailed on," he told the Manchester Evening News.

"But nobody should think of writing them off. That is foolish, but now both of them know for sure they have a couple of players breathing seriously down their necks.

"Arguably there isn't a bigger test in Europe at the moment than facing Drogba and Anelka. But Jonny and Wes held their ground. Neither of the Chelsea forwards could get any change out of them. They didn't win the aerial battle and didn't get behind the United pair."
