Manchester United summer signing Alexander Buttner has been describing the force of the Sir Alex Ferguson hairdryer treatment.

The 23-year-old moved to Old Trafford from Eredivisie club Vitesse Arnhem in a move that was met with some surprised at the time, but Buttner made a terrific debut to his United career by scoring in a 4-0 win over Wigan Athletic.

He was speaking to Dutch magazine Voetbal International when he gave some surprisingly open quotes about Ferguson’s famed blasts of anger at players not carrying out his orders accordingly.

According to Buttner, the Scot is indiscriminate when it comes to handing out dressing downs to his stars, with reputation meaning nothing if his instructions aren’t being carried out to the letter.

The young left-back also claims that the level of fury spouted by the Red Devils boss was unheard of in his native country.

“I've never seen anyone so angry as he can be. It is something that would be unprecedented in the Netherlands, I swear,” he said, as translated by Sport Witness.

“And what is so special is against whom he rages, everybody without distinction. It matters to him not a jot whether it's Rooney, Scholes or Nani. If he does not like it, he flips it full on.

“Especially if you're in the game, doing something wrong because you are tired. There he really hates it.”

It is unusual for Manchester United players to give such detailed accounts of Ferguson’s behaviour in the dressing room and it would not be unreasonable for someone to suggest he may frown upon such an interview.

Major Old Trafford stars have fallen foul of Ferguson’s anger, such as David Beckham or Jaap Stam, and learned that his wroth can lead to a quick exit.
