He's honestly fantastic.
As I pointed out on Discord, Opta revealed that he's played more minutes than all u18 players in Europe combined. Let me tell you why this is insane.
Kid is 17. This is his first full season at pro level. You might think him playing so much means his team lacks options in the midfield, but truth is they're third in the league. They're one of the best teams in the league this season and he's the main reason why.
Like VUKDS said, he's really damn smart. He's a great tackler who always stays on his feet, knows very well how to pick his runs forward and how to end them with a good pass.
He was very decent against Marseille, who is also one of the best teams this season (actually, probably 2nd best after PSG) and whose main strength is their midfield. He's consistently good, but the fact that he stands out against the best teams (mainly his games against PSG and Lyon) tell a lot about his ability to improve at/to a higher level.
I'm not sure about Anchor man. It was a change made by Adrien and I don't have a specific opinion on it, though I can see the reasoning behind it. I wouldn't touch it, but he can probably explain more in depth why he gave this set the card.
Everyone knew it was impossible. Then came along a fool who didn't know it, and he did it.
