The former Deportivo goalkeeper has voiced his opinion that the Los Blancos attacker is flawless, and feels he is finest forward in the history of the game

Former Porto and Deportivo La Coruna man Nuno believes that Cristiano Ronaldo is the best player in the world, and has described the Real Madrid star as "the perfect football machine".The goalkeeper, who was part of Portugal's Euro 2008 squad, is of the opinion that the former Manchester United forward is more complete than any other footballer, and therefore rates him above Barcelona's Lionel Messi, as well as greats such as Pele, Alfredo Di Stefano and Diego Maradona."Messi is a great player, but Cristiano is absolutely tremendous. He is the best in the world because he's the most complete player," Nuno was quoted as saying by AS."He is fast, powerful, scores goals, has so much quality and always helps his team out defensively if needed. He is the perfect 10. I have never seen such a perfect football machine."Football has changed a lot, and I doubt that players such as Pele, Di Stefano and Maradona could do what Cristiano does now with that intensity."Ronaldo netted 46 goals in La Liga in 2011-12, thus helping Madrid to their first league title since 2007-08.Goal.com will be running a dedicated LIVE! on Saturday from 11.00-00.00BST to keep you up to date with all the latest about the Champions League final between Bayern Munich and Chelsea, while also offering you the chance to ask our European football editors any questions you have about the game via Goal.com International's Twitter account, or our Facebook page.
