This lead to reports that he could PSG in the summer but a transfer never materialised.
Since signing for PSG two years ago, Mbappe has helped the French club to win back-to-back Ligue 1 titles and also bagging many goals in the process.
He has scored 38 goals in 36 Ligue 1 games, after emerging as one of the best players in the world.
However, Hazard is clearly a fan of the 20-year-old, who is currently in negotiations with PSG over a new contract.
The Belgian forward said on Sunday that he believes the wonderkid will overtake Lionel Messi and Cristiano Ronaldo as the best player in the world in the coming years.

“In a few years he will be the best player in the world,” Hazard said.
“He is a great talent.
"If he continues like this, Kylian will go down as one of the best players in history.”
Madrid are keen to sign Mbappe, according to reports, and Hazard admitted he wants to help his new side sign the Frenchman.
