And speaking to Dutch television channel RTL, Van Gaal claimed that Mourinho - his former assistant and long-time friend - had been in touch to reveal his awe at his mentor's CV.
"Jose Mourinho was one of the first people that texted me when I got the job," Van Gaal said. "He said that he was jealous of my resume of clubs."
Van Gaal also insisted he does not foresee any problems with Ferguson, who remains on the board of directors at United and previously endorsed Ryan Giggs for the manager's job.
"I will probably have a drink with Sir Alex Ferguson, but we've done that a couple of times before," he added. "We get along quite fine.
"I don't think his pressure will be a big problem. I put a lot of pressure on myself. We need to get United back to the summit, as soon as possible.
"Maybe people will think that this will happen in the first seeason, but we'll have to see. In the end, there's only one team that becomes champions."
