He's a legit wc prospect.
The new generation of midfielders in Brazil class 1998/2000 are all DM/8 or DM-playmakers.
They're not supposed to score many goals, but the best prospects are very strong in defense, great dribbling and pass.
The best imo are:
1 - Wendel(19) Fluminense
2 - Arthur(20)Gremio(shocked that Pep is not going for him)
3 - Douglas
4 - Matheus Fernandes(19)Botafogo - apparently going to Barcelona.
5 -Matheus Jesus(19)Sao Paulo - in fact is the best but he's barely playing due to bad behaviour.
6 - Thiago Maia(20)Santos
All the media and fans think that Douglas, Wendel(Fluminense) and Arthur(Gremio), all U-20, will be the NT midfield after 2018.
Yesterday Tite(Brazil nt coach) said in some event in Porto Alegre that he was following the development of those three players, so Douglas probably would be tested in the next months(not anymore of course).
I think this move is very bad for him.
Was better to let him playing in loan at Vasco like City did with Gabriel.
I never saw this loan-system working for any Brazilian player.
He's not a player that should go to some small spaniard side.
