Former Real Madrid star Roberto Carlos has voiced his opinion that Cristiano Ronaldo deserves to win the Ballon d'Or ahead of Lionel Messi because the Barcelona man has already won plenty of awards in the past few seasons.The Argentine has won the last three editions of the accolade, with his Portuguese counterpart having to settle for second place last term, and missing out on a top-three spot in 2010.Nevertheless, the legendary left-back feels that the Madrid man's time has come now after a successful 2011-12 campaign."Obviously everyone’s talking about Messi, but I reckon he has won enough and there cannot be much more room in his trophy cabinet," he told Fifa.com."Therefore, I would vote for Cristiano Ronaldo. He is someone who can win matches for you in many different ways, from varying situations in attack. He deserves to win it again."The Brazilian then voiced his opinion that Real Madrid coach Jose Mourinho should be named Coach of the Year by Fifa."Well, seeing as Pep Guardiola has left Barcelona, I think it should go to Jose Mourinho."A club side like his is harder to coach than a top national team - something I know a lot about. During my time at Real Madrid, I played under Fabio Capello, who did an amazing job."But when you look at Mourinho’s results, you can see his coaching has a lot of merit and he really knows how to deal with the situations he faces."Mourinho guided Real Madrid to their first Liga title since 2008 last term.
