Hindsight, 20/20. First of all, as I mentioned before, Cristiano Ronaldo looked nowhere as good or special as Mbappe does at 18 and it stayed that way until he turned 22 and slowly became the Cristiano we see today. There was absolutely nothing special about Cristiano, he was a largely ineffective trickster that could barely put a decent sequence together, let alone score boatload of goals. Rooney didn't wrap up a season better than Mbappe until he turned 25. Messi is a once in 25-years talent and was that way from the age of 19.
Doing a hundred step-overs, or an elastico is cute and all, but it's not very effective. You clearly haven't seen enough of Mbappe or you're just not paying attention. He has very good ball control for his age and at his pace. His view of the game is actually what sets him apart from other 18 years old. You just have to watch his game in the CL, especially against Juventus to see he's actually very good at reading the game. I don't know how old you are, but you have terrible memories of Cristiano if you thought he had that special feeling back then, he was a Denilson lite at best until years later. Cristiano Ronaldo is actually the reason why I can't rule anybody out now from becoming a world-class player, because he clearly exceeded his talent's limitations with incredible work-ethic. If Mbappe has even half of his training intensity, he'll be a world-beater as well.
