Cristiano Ronaldo has admitted that he misses Sir Alex Ferguson but worries that his former Manchester United manager's toughness is bad for his heart.
The Real Madrid star quit Old Trafford for the Bernabeu in the summer of 2009 after making almost 200 appearances for Ferguson's side.
Ronaldo won three Barclays Premier League titles, two FA Cups and a Champions League medal during his six-year spell at the Manchester club.
'I really miss him because I have a great relationship with him,' Ronaldo said.
'He's a fantastic person, a human person. He taught me many things. Like I said before, he's like a father in football.'
But Ronaldo admitted the strain of managing one of the biggest clubs in world football could take its toll on the Scotsman.
Asked by CNN World Sport how tough Ferguson can be on his players, Ronaldo replied: 'Very tough. I think sometimes he cannot be like that because, how old is he? 70? It's not good for his heart.
'He's still tough, strong, I remember him the first time I saw him he was with the same power. '
Ronaldo, who has already scored 19 times for Real Madrid, also spoke of fatherhood in the exclusive interview.
'‘I think it’s the best thing in life to have a kid. ‘To wake up in the morning and to see him and say "daddy daddy" it’s like a feeling like if you really have a kid, who will know what I'm talking about. It's great. I love it.’
However, the Portugal captain also revealed he prefers giving his two-year-old son a shower than change his nappy.
