Very little was known about Matteo Guendouzi when he made the £7 million move from FC Lorient to Arsenal this summer.
The 19-year-old had featured in just 30 games for Lorient with the majority of those coming in France's second tier.
But, Arsenal clearly saw something in him, and at the moment the fee they paid for him is looking like a bargain.
Guendouzi has been a regular under Unai Emery this season.
He has already featured in 14 games for The Gunners and has looked assured in the middle of midfield whenever called upon.
Arsenal are currently fifth in the table having picked up 24 points from their opening 12 games with Guendouzi playing a vital role in their early season success.
Fans of the club have quickly taken to him and he was rewarded for his displays by being called up by France U21s for the first time.
So, how did he do on his first outing at that level?
France U21s would draw 2-2 with Croatia U21s and it appears that Guendouzi put in another superb performance.
It seems many in France were impressed by the 19-year-old and L'Equipe even labelled him 'the boss' following the game.
"Everything is going very fast with Mattéo Guendouzi, first selection at the Espoirs, in the early evening against Croatia," The French media outlet wrote about Guendouzi after the game.
"So fast that in ninety minutes, the former Lorient, spent this summer at Arsenal under the orders of Unai Emery, offered a personal performance quite bluffing, in the game, as in attitude.
"By the gestures, the confidence that he releases, by his raids too, including the one that brought the equalising goal of the Blueberries (Bamba, 82nd), Guendouzi gave the impression of being, at 19, the boss."
That just sums his performances up at the moment.
Guendouzi has been impressing whenever he has played this season and many in France are also taking note.
Watch his highlights from his debut below:
Guendouzi praised his teammates for putting him at ease before the game.
"In Arsenal, as in Lorient or with the Espoirs, I will not change, my attitude on the pitch is like that, I always want to win," he said, per L'Equipe.
"It is transcribed by gestures but I do not pay attention. I try to adapt to the team, there is a group that has already worked very well in recent months before my arrival.
"My teammates put me at ease, they made things easier today. I did not feel any particular pressure, I play as I know how to do. "
It seems Guendouzi can do no wrong at the moment.
