Haven't watched him enough to have an opinion. And even if i had, at 18 years old it's impossible to predict (in this case). He could have shown a lot of promise and then flop or simply be average - like PedroFlu says he is - and become a good player like Coutinho. We'll have to wait and see.
Of course they aren't, but I'd trust seperate talent scouts working for 2 elite clubs over a couple of people on a forum who think a player is shit after tuning in to 3 or 4 games in a league they don't care about.
Is he anything special? Maybe not. I don't have a fucking clue. But yeah i'll take Juve/Barca's opinion that he's not 'Shit' or 'crap' over an armchair scout with some time to kill and a Brazilian Serie A stream open.
I'd take him for a good price. People say there's no point because players like him aren't great against packed defences but we've been breaking down packed defences under Conte with a bunch of donkeys up front so I'd happily take a speedster or 2, could come in very handy in Europe
