Cristiano Ronaldo says Jose Mourinho is a better manager than Sir Alex Ferguson.
The Portuguese superstar joined Real Madrid for £80m after six very successful years under Ferguson at Manchester United.
The legendary boss, who has been in charge at Old Trafford for over 25 years, has helped United become one of the most successful clubs in the world - leading them to 12 Premier League titles.
Mourinho, meanwhile, has had success wherever he has gone and is considered one the planet's leading managers.
In just 10 years as a first-team boss, Mourinho has won seven titles in four different countries and the Champions League with both Porto and Inter Milan.
And Ronaldo reckons the 'Special One' is also number one.
"Ferguson was like a father to me," Ronaldo told Marca. "He taught me many things and I had a very nice period with him.
"Mourinho, meanwhile, is the best coach in the world and to be with him now is great to continue growing. It is very good to work with him because he is number one."
