Yeah, like most people, I started seeing his name pop up on Twitter and on football sites this season. I'm a pretty casual fan who likes following young players, and a lot of the accounts I followed have been raving about him for the last year or so... kinda in the same way they did over Davinson Sanchez. Plus, he's been linked with a lot of huge clubs and is on the verge of a full Brazil cap at age 20. In the summer before he even had his breakout season, he finished at 21 in the L'Equipe list of best young players in the world and will likely shoot up it next year.

Again, none of this is scientific and I get if it's not convincing to some. But I do think that from the outside looking in, you can feel like he's a pretty high level prospect and an exciting one for the future. Especially if he's a player that Poch rates highly and has been tracking for a while, I'd be pretty excited if he signed.
