Knight slams nervous United

The defender was part of the Fulham side that lost 2-1 in the FA Cup to United on Saturday.

However, Knight claims his team were not overawed by the pressure of playing United away from home and that they were unlucky not to come away with a positive result.

Sir Alex Ferguson's side squeaked through to the last four thanks to two goals from Ruud van Nistelrooy after Steed Malbranque's penalty had put the visitors in front.

Knight feels the lack of belief will cost The Red Devils in the final few months of the season and that they will struggle to stop Arsenal doing the domestic double this season.

"We knew United's confidence was a bit low and we tried to capitalise on that," he told the London Evening Standard.

"You can feel it when you play against them and there are little arguments between the players when last season there was none of that.

"I think Arsenal will clean up this season. They are out in a league of their own."
