MADRID (Reuters) - Self-proclaimed 'Special One' Jose Mourinho had only one problem with Cristiano Ronaldo when he coached him at Real Madrid -- he thought the world's most expensive player was a bit of a know-it-all.

Ronaldo joined Real from Manchester United for around 90 million euros ($118 million) in 2009 and took his goalscoring exploits to new heights under Mourinho, who left Real Madrid to rejoin Chelsea as manager earlier this week.
