I do wonder about this when you say his attitude stank the place out. I think it's one of those where fans just throw out something we know very little about and make it into truth.
What was said from Ronaldo, and also from teammates was that Ronaldo trained very hard and wanted to help younger players learn from him and improve. What he reacted to was that the younger players weren't interested, didn't train hard nor did they prepare well enough. So he had an issue with the attitude of several teammates. He has been proven right in that respect. He also had an issue with the attitude of the club, and how they had neglected the training facilities, the stadium, some inner power struggles etc - which he was also right about. If anything, the attitude that stank the place out was from several of his teammates who simply didn't put the work in and played like superstars when they weren''t.
Sure, Ronaldo has an ego bigger than the moon, but his dedication to the game and to Manchester United have never really been, nor should it be, in question. Him running off the Piers Morgan was not the right move, and it was detrimental to his legacy and caused far too much harm. On the flip side, United have actually undergone renovations afterwards, and they have put pressure on several of the things that he pointed out. Interestingly, the official United websites, Norway for instance, still post things about him, so perhaps many actually did agree with him.
All that being said, he should not have returned to the PL that late in his career. His first season was good, and I don't think his pace was a problem - he was still more than fast enough, but he became so stiff that he couldn't do what he wanted to anymore.
