Giggs' fitness amazes Ferguson

Manchester United manager Sir Alex Ferguson admits he is delighted for Ryan Giggs after the midfielder signed a new deal.

The 38-year-old has agreed a one-year extension to his current contract that will keep him at Old Trafford until the end of the 2012/13 season.

Giggs has made 22 appearances for United in the current campaign, scoring three goals, and is set to make his 899th appearance for the club against Liverpool on Saturday.

And with the Red Devils on the heels of league leaders Manchester City in the race for the Premier League title, the Welshman has the chance of winning his 13th title this season.

Ferguson has heaped praise on the veteran and confessed that he is amazed by Giggs' endurance.

He said: "I don't know how he does it. It is a miracle.

"His form this season has been the same as the last five or six. His fitness has been incredible and his appetite to play is just the same. We are all delighted."

Giggs is showing few signs of slowing down and has been in the starting line-up for most of the recent games, including the encounters against Liverpool, Arsenal and Chelsea.

He has overcome the problems that affected him midway through his career, when he had ongoing hamstring and back injuries.

But yoga appears to have controlled his difficulties and Ferguson has praised Giggs for how he has coped.

He said: "We used to think he had spasms in his hamstrings, which were related to his back.

"When he started doing the yoga, all that disappeared.

"The youngsters couldn't have a better mentor. Ryan and Paul Scholes are different types of midfield players but they have proved by their dedication that you can play to that age."
