Manchester United veteran Ryan Giggs cannot guarantee he will play on next season.

United boss Sir Alex Ferguson claimed his long-serving star is capable of playing on for another year.

Giggs, who turns 40 in November but is out of contract in the summer, said: "I don't know if I'll have another year.

"I'm probably enjoying it now more than ever.

"If you don't enjoy the FA Cup at Old Trafford then you should pack it in, but we'll see what this season brings."
