Real Madrid star Cristiano Ronaldo admits he struggles when critics take aim at his private life. Ronaldo is happy for people to judge his form on the field, but that is all.

"Criticism is part of our business, we have to live with it," said Ronaldo, 28, in GQ magazine.

"The thing that hurts me is the criticism of matters outside the pitch. It does not bother me when it comes to my game, because I am the first to realise it."
