Having burst onto the scene with Monaco by plundering 26 goals in 44 games as they surprised onlookers by edging out PSG to claim the Ligue 1 title and reached the Champions League semi-finals in 2016/17, there was plenty of pressure on the then-18-year-old's shoulders to prove he was not simply a flash in the pan.
A big-money move to PSG followed and whilst his debut season in the French capital wasn't quite as spectacular as his previous campaign in the principailty in terms of pure goals, there were plenty of signs that the Bondy-born sensation was here to stay.
Having been shunted out wide to accomodate Neymar and Edinson Cavani, there were plenty of occasions during the course of the campaign when the starlet outshone his bigger-name team-mates.
With his career very much still in its infancy, Mbappé aready has two Ligue 1 titles, a Coupe de France and a Coupe de la Ligue under his belt domestically and even claimed the World Cup with France this summer despite it being just two years since he was winning the European Championship with the U19s.
Such is his quality that he is rarely compared to players of his own age, but rather with some of the biggest names in world football.
Not that competing with the big boys is anything new for him, with AS Bondy president Atmane Airouche having previously said this about a young Mbappé: "He had technique and vision in the game that most children just don't have. He's got eyes in the back of his head. He knows how to anticipate where the ball will go. Here, he never played for his proper age group, he always played with older children because there was no point leaving him with kids his own age."
He returned from the World Cup in Russia as the best young player and joint second-highest goal scorer at the tournament just a year after being named the best young player in the world as he picked up the much sought-after Golden Boy award.
His latest individual gong came on Monday night as he was included in the FIFPro World XI, leading the line alongside Cristiano Ronaldo and Lionel Messi.
In a world where youngsters are overhyped by the media from an increasingly young age, Mbappé mix of jaw-dropping ability and enviable temperament mark him out as someone who could genuinely go on and become the best in the world.
