Jose Mourinho has opened up on how he turned Cristiano Ronaldo into a goalscoring superstar at Real Madrid.

Mourinho arrived at Los Blancos in 2010 - a year after they had broken the bank to sign Ronaldo from Manchester United in a record-breaking £80million deal.

Eyebrows were raised over the astronomical fee at the time, but if one player justified breaking that ceiling, it was Ronaldo.

In his debut season at Real, the Portuguese star was an instant hero as he chipped in with 33 goals in all competitions.

However, after Mourinho arrived, Ronaldo's game propelled into the stratosphere - scoring 53 times the following campaign - then 60 the next and 55 the year after that.

Talking to Ronaldo's ex-United teammate Rio Ferdinand, on his YouTube channel Five, Mourinho explained the secret to getting the five-time Ballon d'Or winner to perform.

"Motivation, you don't need to give him. Ambition, responsibility, you cannot give him. Technically, you cannot give him," the 61-year-old said, who managed Real for three years.

"It's just to give him some tactical adjustments and let the guy be happy."

And despite managing some of the biggest egos in world football throughout his career, the Special One has insisted he was happy for Ronaldo to do his own thing.

He remarked: "I think you don't coach. I don't have to teach much, it is about being happy, it is about creating an environment by the tactical point of view, by the idea of football where the player can show his best.
