Giggs is currently 43 games away from matching Sir Bobby Charlton's club best of 759.
Theoretically that could be done next season but in reality, at 33, Giggs is unlikely to be pushed quite so hard.
With his contract due to expire in 12 months, there was the real possibility Giggs may leave Old Trafford before he beats Charlton's record.
But, while chief executive David Gill confirmed earlier this week no talks were planned with the former Wales international, Ferguson confirmed both Giggs and fellow veteran Paul Scholes, would be remaining at United for a long time yet.
"The situation with them both is straightforward," said the United boss.
"They are both fantastic professionals who have looked after themselves properly.
"I don't have any doubts about them. They are both going to be playing at a very high level well into their mid-30s, certainly next year and the year after."
While Giggs turned in a man-of-the-match performance in a 6-0 triumph over Shenzhen in Macau on Monday night, Scholes was heading back to England for further tests on the knee injury he sustained in Seoul on Friday.
Although Ferguson does not believe the damage to be too serious, the former England star has been ruled out for up to a month, a period which includes the Premier League opener against Reading on August 12 and subsequent trips to Portsmouth and Manchester City.
With fellow midfielder Owen Hargreaves yet to play a part in United's pre-season campaign so far due to his own knee problem, Ferguson could have done without such bad news.
