Louis van Gaal berated his side after their 3-0 defeat against Everton over the weekend according to the Daily Mirror.
The paper also claims that the Dutch boss singled out both Anotnio Valencia and Daley Blind for their performances in the loss at Goodison Park which dropped the Red Devils down to fourth.
Goals from James McCarthy, John Stones and Kevin Mirallas consigned Manchester United to their second defeat in a row, although rivals Liverpool failed to capitalise after falling to a 1-0 defeat against relegation threatened Hull last night.

According to the Mirror, Van Gaal could barely contain his anger after the game and embarked on a Sir Alex Ferguson-style 'hairdryer' rant, while he was said to still be furious when he took training with his team the following day.
Both Blind and Valencia were subjects of the former Bayern Munich manager's wrath for their role in McCarthy's opener after just five minutes. Valencia, who has been deployed as a make-shift full-back this season, also could have done better as the Toffees their advantage ten minutes before half-time.

An upset Valencia reportedly turned up over two hours late on Monday afternoon to meet competition winners from United’s 'Social Casino' partner.
The Dutch boss was more measured when dealing with the press after the full-time whistle, although he still described Manchester United's efforts as their worst of the season.
“I think it was the most disappointing performance because it is the first time that I have seen our motivation, inspiration and aggression was not as high as the opponent," he said.
"In sport you shall always be compared to your opponent and that was the reason. I had already the feeling and my colleagues Ryan Giggs and Albert [Stuivenberg] had the feeling because the warm-up was not so good as usual.
"You hope you can recover and stimulate your players by saying something before the game but by then it is too late. You have to prepare the match two or three days before. Everton did that and they have won because of that.”
Manchester United were terrible against Everton, and they got the result their performance deserved. Van Gaal was right to tear into them, although to single out Valencia and Blind seems a little cruel as the entire starting XI weren't exactly on their game.
It is interesting to note that Van Gaal saw lethargy in the warm-up and knew the result was coming. With Liverpool dropping points Manchester United have been let off the hook, and it will be fascinating to see how they react against West Brom.
