Ollie wrote in the Sunday Mirror: "Cristiano Ronaldo splits opinion. You love him or you hate him.
"Sometimes you feel both emotions.
"But I have got to say that when it comes to being a professional footballer, you can only admire the bloke.
"Ronaldo won his 100th cap for Portugal against Northern Ireland in midweek at the age of just 27 years and 248 days.

"Playing for your country used to be the pinnacle. Now it's become a chore that's best to be avoided when you are your club's most prized asset.
