Real Madrid fans boo Ronaldo after Barcelona comments

Real Madrid star Cristiano Ronaldo was booed by Madrid fans this week at the tennis.

Sport says Ronaldo was booed by spectators on Wednesday when he attended Rafael Nadal's match with Oleksandr Dolgopolov.

It's suggested Ronaldo has infuriated some fans by refusing to rule out the prospect of a future move to Barcelona.

"Barca? At this time, Madrid is my home and my club Real Madrid but I can never say never. I do not know what will happen in the future, you never know, although I would like retire in Madrid," said Ronaldo.
