Sir Alex Ferguson was known for giving players the 'hairdryer' treatment from time to time as Manchester United boss.
The term referred to the way in which the Scot would scream in the face of an individual, and it seems no player was exempt from a Ferguson rebuke.
Cristiano Ronaldo was one of four world-class players - by Ferguson's own admission - that the legendary Red Devils boss managed during his time at the club.
And the Portuguese forward found himself on the wrong end of a rollicking from Ferguson not long after he had signed from Sporting Lisbon, according to Nemanja Vidic.

"I think Ronaldo wasn't happy when he [Sir Alex] shouted at him," Vidic told the League of Legends podcast.
"In the beginning it was one time he said something to Ronaldo, but he accepted it very emotionally.
"He took it personally, but he was very young - he was 20 years old."

Ferguson was successful for a number of reasons, but his willingness and ability to adapt is perhaps the key to his longevity.
And, according to Vidic, Ferguson changed the way in which he addressed Ronaldo from that moment onward so as not to knock his confidence.

"Of course you realise, even me, that next time you will not tell him [if he does something wrong]," said Vidic.
"It's better to not tell him because otherwise he will be too emotional and he won't help you be better."
