‘You have guys like Cristiano, where you are playing against Levante and you are winning five-nil and you tell the guy to relax and take a rest,’ Football.com global ambassador Mourinho said.

‘No, no, no, I can score one more goal!’ When you have guys like this, you know the boat is in the water and you just let the boat go and in the end you enjoy the fight.’

Jose Mourinho has spoken about how he used to argue with Cristiano Ronaldo when it came to substituting the superstar off at Real Madrid

Mourinho said Ronaldo is so naturally talented and determined you don’t need to coach him

Mourinho was talking about the intense rivalry between his Real side and Guardiola’s stylish Barcelona team which boasted Lionel Messi, Xavi and Andres Iniesta.

In his first season, Real beat Barcelona 1-0 in the Copa del Rey final thanks to Ronaldo’s towering header in extra time, before they pipped their rivals to the LaLiga title the following year.

‘For us to win the league, we did 100 points. You knew that if you didn’t do 98, 99, 100, you don’t win it,’ Mourinho added.

‘You are then in trouble because Barcelona wins and the next season, the previous season, when Barcelona wins. I think we lost with 92 points or 91 points, something like that.

‘So you know that if you made a mistake, you are in trouble.’

Asked about what it was like to work with Ronaldo each day on the training ground, Mourinho said the player’s natural abilities made him a dream to work with.

‘I think you don’t coach [him]. You don’t teach much, it’s about being happy and it’s about creating an environment from the tactical point of view, from the ideas of football, where the player can show,’ he said.

‘Madrid for him was a little bit of a transition because for you he was a winger – left winger, right winger, dribbling, attacking people, beating people.

‘In Madrid, he became more the goalscorer that he was for the rest of his career.

‘In fact, probably the first time he played a big match as a striker was Real Madrid vs Barcelona in a cup final where he scored an amazing goal with an amazing header in extra time.

‘Probably that was the first time people got the feeling that animal could be a goalscorer and not just a pure winger.

‘Madrid was a bit of a hybrid because he was playing from the left but he was not wide and not chasing full-backs and we were protecting him with the balance being with Xabi Alonso and Sami Khedira.

‘That is the position when they can be more effective and score more goals.

‘Cristiano, you know him as well as I do and almost in consecutive years. Motivation, you don’t need to give him. Ambition, you don’t need to give him. Technique, you don’t need to give him.

‘You give some tactical adjustments and let the guy be happy.’
