Louis van Gaal says the expectation levels among the supporters have had an adverse affect on the Manchester United squad.
United are facing a season of disappointment as it looks highly likely they will miss out on a top-four finish and Champions League football.
The Old Trafford side have the second-most expensively assembled squad in the Premier League, behind only Manchester City, but Van Gaal believes expectations are “too high” as the club are in a “period of transition”.
The Dutchman also blasted large sections of the media for regular claims he could be axed by the club’s hierarchy, which he feels have also impacted on his side’s performances.
Speaking at the club’s end of season awards, he said: “I’m a coach, a manager who would rather have some authority but every day the players can read it, what do you think about my authority as well? What do you think about the way they want to follow my advice when the coach is shown like a nobody?
“And I am not what the media is writing because I am very arrogant, because I am one of the best managers in the world.”
Van Gaal does have a chance to pick up some silverware this season as United will take on Crystal Palace in the FA Cup final.
The manager hopes to get his hands on the trophy, but he believes the fans need to lower their expectations regardless as he has concerns the players are struggling under the pressure.
He added: “I am happy to give the fans a final. The expectations are too high. We are in a period of transition. The players feel that. It’s not so easy.”
