I'm okay with criticizing, pointing out weaknesses in his game, fair discussion from both sides. I'll always be more inclined to bring out the positives from him and it's only fair someone else balances it out by trying to bring out his weaknesses. It's not unreasonable to think he might've been done at 37, but just from those who look to him as just another dude going on about playing football - it's just he's a freak of mentality, and some people don't understand that, which is okay, either through not being able to follow the entire career, or something else, it's fair.
I'm not sure he's a solution either to be honest - there's too many things wrong with United and one man can only help so much. Look no further than this season, you have him performing week in week out except for that 2 month spell, and the end result is what we all know. Maybe the team needs something else other than him. Maybe United needs to bring players to match Ronaldo's quality and mentality. At this point I don't know to be fair. The only thing I feel confident about is that he's definitely not a problem right now, considering everything else surrounding him.
It's just incredible some people actually had the guts to come here and say he was just another finished guy that came here for vacations and syphoning money out of the club. Apart from that extremism (which admitedly, as someone else pointed out at the start of this page, also exists to the other side), I'm all for a decent, respectful conversation, on all things positive or negative regarding him.
