Many believe it will be Mbappe who will succeed Messi as the world's best player.
On the Ballon d'Or, Mbappe said: "Last season, I realised I could challenge for it. But in front of it stood Messi. I would score two goals, he would three; I scored three and he scored four. It's crazy.
"I talked to Ousmane Dembele about how that was possible, and if he saw the goals I scored. And he told me that Messi was watching me.
"It's flattering that someone like Leo takes you into consideration."
