Manchester United manager Sir Alex Ferguson has no doubts that Ryan Giggs can continue playing for the club for another few years.

The midfielder signed a new one-year extension on his current contract earlier this month that will take him into the age of 40 and see him join Gordon Strachan and former United teammate Teddy Sheringham in an exclusive veterans' club.

However, Ferguson believes that Giggs can surpass the duo and break the record for the oldest outfield player in Premier League history.

"Ryan is an exceptional human being," Ferguson told US radio station Sirius XM. "He has never carried any weight, has never suffered a serious injury and never misses a training session. He is still at the head of the pack during pre-season.

"He just has this insatiable appetite to continue playing. He will play next year and who knows he could possibly play for another year after that.

"I am sure he will get to 41 and still be playing because he is such a fit lad."

Giggs has won 12 Premier League titles, four FA Cups, three League Cups and two Champions League winner's medals during his time at Old Trafford.
