Manchester United midfielder Darren Fletcher doesn't believe their clash at Chelsea will be decisive.

Many believe defeat could be too much for United to haul in table leaders Chelsea.

But Fletcher says: "Sunday is a massive game. Games against Chelsea always are.

"It is not going to make-or-break who wins the league by any means, although it is an important benchmark.

"Maybe psychologically it might have an effect. But Chelsea are a top-class side and we will respect them."

He also remarked: "We have had a couple of draws down there but we have still not managed to win in the league and we are desperate to do it.

"But we will go there with a game-plan and try to get a result."
