Former Manchester United boss Sir Alex Ferguson admits losing his rag with today's players is a no-no.
He claims he had to turn down his famous hairdryer in his last years in charge at United because players nowadays are more fragile.
"The human beings I've dealt with are far more fragile than the human beings of 30 years ago," he said.
"And I say that in a good sense because they're coming from better conditions. I couldn't lose my temper the way I did back then with people nowadays.
"Also, which has become very dominant in the English game, is the culture of players from different countries.
"At United I think there are people from 20 different nationalities and that's a challenge because people from different cultures have to be addressed.
"You have to make sure that they are comfortable in their environment because it's a results industry and you need to get the best out of them."
