Manchester United striker Wayne Rooney admits he wasn't at his best for their draw at Swansea City. Fuming Manchester United boss Sir Alex Ferguson slammed Rooney on Sunday, insisting his performance was not good enough after substituting him in the 1-1 draw at Swansea.

And the England striker is anxious to make amends against Newcastle United at Old Trafford today to keep United on course for a record 20th title.

He admitted: "Some days you have an off-day and I could feel it on the pitch against Swansea.

"I couldn't complain at being substituted.

"The Swansea game has gone and it is certainly not one I will remember - but I will relish the next one.

"We are happy to be four points clear at the top. We are still in a good position with two home games coming up. We need to make sure we take maximum points from them.

"It's early days and there is a long way to go but we are in a healthy position at the moment."
