Ryan Giggs is serving as Louis van Gaal's number two and is widely expected to be the club's next manager.
Giggs retired last season as a player and served as interim following the firing of David Moyes.
"I expect that he [Giggs] will be the next manager after I am gone," said Van Gaal.
"Now I have the responsibility. He has tasks that he has to perform like the players. What he has to do, for me, he does it very well.”
