Sir Alex Ferguson is of the belief that the 'insatiable appetite' of Ryan Giggs to continue his playing days will see the Manchester United star become the oldest outfield player in the history of the Premier League.
Giggs has agreed to prolong his Old Trafford career by another season, taking the veteran midfielder into his 24th year in the Manchester United first-team, which will guarantee the Welshman will be playing beyond his 40th birthday.
The 12-time title winner, with number 13 surely just around the corner, reaches the age of 40 in November, and Ferguson expects Giggs to continue playing well past that significant milestone.
Ferguson has lavished praise on the player he signed for Manchester United on his 14th birthday, and believes Giggs' incredible fitness and attitude to training almost guarantees he will break the Premier League's record, which is currently held by Teddy Sheringham.
"Ryan is an exceptional human being," Ferguson told 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 played 933 times for Manchester United in 22 seasons at Old Trafford and, should Ferguson's assertion come true, he could be the first Red Devil to reach 1000 games for the club.
