I'm with AvadaKedavra on this. The kid is doing very well for the Primavera side, showing some impressive skill on the ball and a good passing range; he's a very important cog in the machine there and his style of play needs that sort of importance for him to actually make a difference.
We don't really need him in the first team squad either, as we currently have three players that can play the position he does in our line-up in Sneijder, Alvarez and Coutinho. With all three of them fit, it'd be a really pointless to bring him up to the first squad to sit on the bench (at most).
