How is that exactly your point ? Are you seriously trying to say Man united were only amazing because of Ronaldo ? They'v been amazing in the past, amazing now and will be amazing for years to come and that's all down to one man, Alex Ferguson. And if Ronaldo is so spectacular, like you say, and can turn teams "amazing", why are Portugal still shit even with him as captain ? You're contradicting yourself a bit here.
What evidence even suggests that ? When has Ronaldo ever been in a team that's not been amazing ? Man Utd, they were amazing, Real madrid, their amazing, Portugal ? Oh no wait, their shite, and he doesn't seem to be doing much carrying there .
