One time Madrid coach Fabio Capello has named Ronaldo, former Brazil international as the best he had ever coached and most troublesome.
Fabio Capello coached Ronaldo at Real Madrid in 2006, but had to sell him to Milan.
Capello has now revealed Ronaldo returned to camp overweight, and would not respect him.
“Ronaldo, the phenomenon, was the greatest player I have ever coached,” the Italian coach said.
“He showed up [for pre-season] in Madrid and was 96kg, so I asked him to get to 88-90 kg.
“There was nothing I could do. He was a great player, but a negative influence for the group.”
Ronaldo was shown the Madrid door in the January transfer window before Capello’s men recovered from a deficit to overtake Barcelona and win La Liga.
