The Brazilian Ronaldo had quite a few personal and attitude issues. He thought he doesn't need to train, he partied like an animal and so on. Disregarding your football skills, being the GOAT you also need to be an example for kids and everyone else. Ronaldo N., George Best, and quite a few others can't even get close to being GOAT just for this sole reason. Same with Maradona and even Zidane.
If you want to be considered GOAT you need to set the bar not only as a football player but as a man as well, at least, that's my view on it.
In regards to Messi vs CR, I think they're equal, they're at a level where you just can't separate them anymore, it's impossible. That's what hard work and professionalism gets you and they truly deserve their places as the best 2 players in history. I don't think we should remember one being the better player, I think we should remember them setting the bar higher and higher each season, competing at the highest levels for >10 years against each other. We should also remember that no other football player came close to their numbers/quality in the last 10-12 years.(even if some of them might have won a ballon d'or, Iniesta/Suarez)
I like them both, even if they're not my all time fav players. What I don't like is that Ronny thinks that everything spins around him and that Messi, when he or his team are doing bad, just walks around on the pitch doing shite, that's disrespect for your teammates and it should never happen. But other than that, they're truly examples for the football world and they truly deserve their spots as the absolute best football players in history.
