Cristiano Ronaldo is the greatest footballer I have ever seen in my lifetime. My Dad says that he probably is the best he has ever seen too, although Johan Cruyff of Holland and Ajax came close, but was far less consistent. And as for Ronalinho, he isn't in the same class as Ronaldo, even at his best, Ronaldinho was only good for about 5 matches, bad for 1 and back to his best again, but Ronaldo is good in every game he plays, and hes a delight to watch as well, and I can only see him getting better, and when was the last time he got injured? Exactly. Kaka has been injured quite a few times this season at AC Milan and Ronaldinho's season is over because of injury and he looks set to leave for AC in the summer. Manchester Utd have every right to call themsleves the best team in the world at the moment, as I think they'll stroll the league which everybody believes to be the best in the world and in my opinions, they are the favourites for the Champions League too, as Barcelona could only manage 2 goals in 2 games against Schalke, so I don't think they'll be as tough as we think, but we'll see about that. But in my opinion, Cristiano Ronaldo is the greatest footballer that has ever lived, as the standard now is a lot better than 30-40 years ago when the likes of Eusebio, Pele and Cruyff were playing. And also, to get that many goals coming in off teh wing, is quite amazing. And hes got no weaknesses. Hes strong, quick, tall, got an absolutely unbelievable pair of feet and he is one of the best players in this league in the air too.
