Meanwhile, Ronaldo has explained why he never voted for Zinedine Zidane as FIFA coach of the year. 

Ronaldo picked Portugal manager Fernando Santos over his Real Madrid boss but said: 'In my opinion is it much more difficult to win the European Championship with Portugal than the Champions League. 

'It was a very difficult decision between my two managers and that is why I decided as I did. It has got nothing to do with my relationship [with Zidane]. 

'I have a good relationship`with both my coaches. I think in my shoes they would have voted the same.'
