You need to read this whole thing again, as you are getting it all wrong.
Point being, Greenwood are being hyped as teenage generational talent last season, when he was being compared with Mbappe, Haaland, L.Ronaldo, Owen, Rooney etc during their teenage years. But those players mentioned has developed even further when they are 19 etc, while Greenwood hasn't, at least so far up to this point.
Messi and Ronaldo was never mentioned in the same tier as those mentioned in their teenage years, they are never included as the best generational type of teenage talent comparable to those players, as their insane development only starts at around age 21-23.
Basically I am only comparing "tier 1" teenage talents, Greenwood isn't up to this rank. Not saying he won't be great in future, as I 've already mentioned before, and I am repeating for the 3rd or 4th time here: he could still be GOAT in future, but thats not what my discussion is about, as I am only comparing teenage talents.
