Cristiano Ronaldo reveals the finer details of Sir Alex Ferguson’s infamous hairdryer treatment

Cristiano Ronaldo has given an insight into Sir Alex Ferguson's infamous hairdryer treatment.

The Real Madrid man, who played under Ferguson at Manchester United between 2003 and 2009, was speaking ahead of the BBC's upcoming documentary, 'Sir Alex Ferguson: Secrets of Success,' which will be aired on October 11. "I remember sometimes when we do something bad or we lost some games he kick the chairs and he kick the boots, he kick everything, the waters, the drinks, and he’s so red and ‘f**k you, you should pass the ball you," Ronaldo said. The three-time Ballon D'Or winner was far from critical of feeling Ferguson's wrath, claiming it had a positive impact over all. "It was unbelievable but it was good - because we learn."
