Wayne Rooney says feeling the full force of Sir Alex Ferguson¿s rage is 'horrible', but has admitted he sometimes shouts back.
Ferguson is famous for giving his players the 'hairdryer' treatment when they are not performing to the required standard, and Rooney admits he has been on the receiving end on several occasions.
The striker says his manager is still a formidable figure, even if he sometimes decides to disagree and answer back.
"There's nothing worse than getting the 'hairdryer' from Sir Alex," Rooney said in his autobiography My Decade, as reported in The Daily Mirror.
"When it happens, the manager stands in the middle of the room and loses it at me. He gets right up in my face and shouts.
"It feels like I've put my head in front of a BaByliss Turbo Power 2200. It's horrible.
"I don't like getting shouted at by anyone. It's hard for me to take, so sometimes I shout back.
"I tell him he's wrong and I'm right."
Rooney says some players struggle to recover from a blast of Ferguson's anger and their confidence remains shattered.
"I don¿t like getting shouted at by anyone. It¿s hard for me to take, so sometimes I shout back. I tell him he¿s wrong and I¿m right."
