It's a nice set I just think you overrated him a bit, I just have watch some games of him most in SUB-20 so I may be wrong:
ATT: 64 (This ATK is very high he should be bellow Juan(Roma), even he being capable of play as SB he don't deserve to be in pair with Mario Fernandes, who is a lot more suitable to attack.)
DEF: 77 (IMO he is not 2 points over Neuton, neither deserve to be with the same value of L. Castan, L. Euzebio or Manoel, with 77 he would e in pair with Dedé.)
RES: 78 (This value is the one that I disagree more, 82 puts him between the best tackles in Brazilian League, IMO should have 2 points between him and Bolivar.)
AGG: 68 (He is not aggressive has, T. SIlva, Pique, Chicão or Miranda, 68 is more than enough.)
I have some doubts about TW and Form, I don't see any reason to be so high his TW and he don't even had time to show that deserve 7 but he is young and generally young player can play a lot of consecutive matches.
