The 35 year old feels that his standards have taken a dip of late and although boss Alex Ferguson wants his current crop of youngsters to use the ginger one as an example to themselves, the player has not given any hint as to whether he would be interested in a new contraact.
"I wouldn’t say I am playing some of my best football," he said.
"I don’t always feel I am making as much of a contribution as I’d like to.
"I always preferred it when I was playing regularly and scoring a lot more goals. Now, it’s different.
"I play once every two or three weeks and I can only hope to do well when I get the chance. I don’t have a choice.
"Obviously, every player wants to play every week but I know now it can’t always happen. I just have to be okay with that."
And as for his future?
"You do think about it. I’m not too sure.
"I’ll just carry on with the way it it’s going at the moment and we’ll see what happens come the end of the season."
