Goals grab the headlines, so given Ethan’s position is a midfielder he is unlikely to outshine his brother in that department.

But the youngster is seen as an exciting talent in his own right.

His mentality was praised as he broke through from the PSG youth system, appearing to cope well with the weight of expectation that came with being an Mbappe.

Laurent Glaize, a former head of youth recruitment at Caen, spent three years tracking a young Kylian and became close to the Mbappe family during that time.

Speaking about Ethan in 2022, he told TNT Sports: “He is a balanced, well-educated kid who is respectful even if he is obviously in the shadow of his brother, which is not easy for him.

“But I find him calm and with a real personality. I find that he manages this pressure rather well. He does not mistake where he is in the game, even if he is already being asked for autographs more for his name, than for what he has done, because he is still very young.”

Praised for his football intelligence, calmness on the ball and passing ability, Ethan impressed the coaches at PSG and was given his league debut at just 16, coming on as a late substitute in a 3-1 win against Metz, with Kylian having scored two of the goals.

“Ethan is a very interesting player who can play in several positions,” PSG boss Luis Enrique said after that game.

“I am sure he will play again. He has a prestigious surname, which is difficult to live up to.”

In total, he made five appearances for PSG before leaving at the end of his contract last summer, although there was some controversy around his departure.

Kylian has previously implied, external that Ethan not getting a new contract at PSG was linked to his decision to leave and join Real Madrid, and was willing to instead stay at the French giants if it meant his brother got a new deal there also.

“It’s the thing that affected me the most,” Kylian said.

“He [Ethan], didn’t ask for anything. His Real Madrid was PSG. What Real meant to me, his childhood dream, was PSG.

“At one point, I even told him: ‘If you want me to, I’ll extend [my contract] and you can stay, we’ll stay here.’ I would have given up my dream of Madrid and stayed for him.

“Ethan told me… ‘I don’t want to stay here. What they did to you, what they did to me, it’s not normal.’ If he had told me, ‘Kylian, it’s what I want’, I would have given up my dream of Madrid and stayed for him.”
