Prior to handing out the Sir Bobby Charlton Award to Player of the Season David De Gea, the Dutchman slammed the media for the speculation surrounding his job.
Van Gaal praised United for reaching the FA Cup final and challenging for the top four during a time of transition at Old Trafford.
He said: "The expectations are too high. We are in a period of transition. It’s not so easy.
"But what they have shown, when the media is writing for six months that I am sacked, I can cope because I’ve had it at my former clubs, but for my players it’s not so easy.
"I am a coach, a manager, who has some authority, and they are reading what it is said in the press every day, so what do you think about my authority to train?
"So what do you think about the way they want to follow my advice? When the coach is shown like a nobody.
"I am no what the media is writing, because I am very arrogant, because I am one of the best managers in the world, so it is very difficult for them to cope with that.
"But they have done it. We are in the final, we are still in the face for the top four, it is fantastic."
United return to Premier League action on Saturday when they travel to Norwich who are fighting for their top flight survival.
