people should also look at trajectory. Go see what elite wingers were doing at his age. There are very few players who were producing more than him. Go look at Vini, Salah, etc at the same age. Largely producing less.
One thing to remember about the truly top players, is that they have a big spread amongst themselves, as is the case with any talent pool. So a Messi might be blowing the lights out at 22, but the guys the level below him are still significantly better than the rest of the talent pool.
