"If United had seven players out every week they would have found it difficult. It's the same old story for us but we'll just get on with it." And Ferguson also criticised Grant. He said: "I don't know why he says that there might be something untoward. He should know better."
Hammers midfielder Scott Parker agreed with his manager and said that the players' were determined to hold on to tenth spot - they are five points clear of Spurs - in the table.
Parker said: "Me, ease up? I don't know how, really. I will keep playing and tackling the way I normally do.
"Of course it's a massive game for United and Chelsea but from where I am it's a big game for us as well.
"We want to finish in that tenth spot. We're certainly not going to roll over. We're professional footballers and we take pride in what we do."
