Mbappe won a world Cup as a teenager and got to a final 4 years later (putting in outstanding performances)...Messi gets balloon d'or for winning a world Cup scoring almost all penalties ...I'd say mbappe could be ahead of Ronaldo & Messi when it's all said & done.
The balloon d'or is a farce so we can't judge a player based on the awards alone...ask eriling haaland
He's not overrated...just injury prone. And man u knew that before they purchased his services
