Van Gaal fell out with Rivaldo during his time in charge of Barcelona and let Rafael leave Old Trafford this summer.
This has led to accusations that van Gaal isn’t fond of Brazilians but Pereira insisted this isn’t the case.
The youngster addressed his relationship with van Gaal and revealed that he is to be given an opportunity in the first-team at United soon after an impressive U20 World Cup earlier this year.
“My relationship with him [Van Gaal] is normal, just like all the players. I don’t think he had this business with Brazilians, no,” Pereira said.
“Everyone says that he sends Brazilians away, it’s not so. He treats me normal and equal to everyone. I don’t think he has anything against Brazilians. Everyone can say what they want, but with me it’s going good.
“The World Cup helped a lot. When I returned [to United], the manager liked it a lot. For me, it was a great pre-season, I played well in games, and participated in the majority.
“The manager said he didn’t want me to be loaned. He said I had to have patience, that I had to continue working hard, that he would give me an opportunity.”
Pereira was one of United’s standout players on the pre-season tour of the United States and it is only a matter of time before he is given an opportunity in the starting XI. It may come sooner rather than later, as United begin their League Cup campaign against Ipswich Town on the 23rd September.
