Kylian Mbappe's 15-year-old brother Ethan Mbappe makes PSG debut

Ethan Mbappe made his first-team debut for Paris Saint-Germain during a mid-season friendly against Paris FC earlier today.

He follows in the footsteps of his older brother Kylian Mbappe, who is gearing up for a second consecutive World Cup final with France.

The 15-year-old came on for the second half, replacing Fabian Ruiz in what was a ceremonial moment for the player.

PSG triumphed 2-1 on the day thanks to goals from Nordi Mukiele and Ismael Gharbi.

Following the game, Mbappe revealed his thoughts on his debut on Instagram: “Very excited for my debut in the pros,” was the caption which accompanied two pictures of Mbappe in action for the French champions.

Joining the academy set-up in 2017, he has clearly developed well over the years, as featuring in the first-team as an Under-16 player is no small feat.

Additionally, he made his debut for the Under-16 national side recently as well, and produced a solid debut performance against Paris.

Sitting relatively deep in midfield, his highlights show some neat touches, tidy play and a few searching through balls to the right wing.

One user made this claim on Mbappe's style of play: "He plays more like Rabiot/Camavinga than his brother."

Whilst another sympathized with the young midfielder: "Most likely he's to be described as someone's brother for the rest of his life."

Whilst Mbappe is chasing World Cup glory as a 23-year-old perhaps, in the coming years, if he decides to stay at PSG that is, the two brothers may feature together on the pitch at the Parc des Princes sometime in the future.

It would be a great moment if both of them could re-create the now iconic Mbappe celebration together - after all, it was Ethan who is the reason for Kylian's arms-folding celebration thanks to their many battles playing PlayStation.

What a moment that would be. It would almost certainly break the internet and the pair will surely be eyeing up a chance to play together before the older sibling leaves PSG in the future.

If he goes onto have half the career Kylian has, Ethan would be a very special player. But for now, he'll continue to develop, and it's worth remembering that he is still only 15.
