Van Gaal says his job as Manchester United manager is secure, despite recording a fourth straight defeat, after falling 2-0 to Stoke.
Stoke City led a comfortable win with goals from Bojan and Arnautovic piling pressure on Van Gaal.
And the availability of Mourinho has put more pressure on Van Gaal who is certain of his job.
The Dutch coach was asked after the game if Ed Woodward should come out and give him his backing to which Van Gaal told reporters: “That’s always the question in this situation. But I feel the support of everybody in the club.
“People are saying that to me. I am not so interested in public announcements.”
However, when asked if he felt he would be in charge on Monday, Van Gaal added: “The club doesn’t have to fire or sack me, sometimes I do it by myself.
“I am the one who wants to speak first with the board of Manchester United, or with the staff, or with the players, not with you.
“We have to wait and see, but I think so.”
