Ryan Giggs could continue his career into his 40s but will save decisions on a new contract until the end of the season.
The 39-year-old has made 16 appearances for United this season and is likely to be handed yet another one year contract in the summer.
He earned high praise from his manager, Sir Alex Ferguson, for his performance in the FA Cup draw with West Ham. Especially for his long looping pass which set up Robin Van Persie's dramatic equaliser.
"I will see how I feel and see how I am contributing, and then I will sit down and talk to the manager," Giggs told the Sunday People.
"I am cool with that. I am enjoying my football at the moment, but the end of the season is a few months away and you never know what will happen.
"I have to contribute as well as enjoying both training and playing."
Giggs credited Ferguson with managing his fitness to allow him to play on.
"In a way I suppose I get an easier ride than some of the younger lads, and that's because the manager recognises I have different needs at this point," he said.
"But don't get me wrong, my fitness has to be spot on, otherwise I just couldn't compete with the rest of the guys either in training or during matches."
