Strictly speaking Barca B and Juvenil A right now. Anything below is too early to judge. And Alena is with the 1st team so I'm not counting him as he's made the step up and I believe will be valuable to the team even if it is as a super sub.
He's a promising talent, but I fear he suffers from the same limitations as Sergio, without the elite talent, and with football evolving and teams wanting players that are more aggressive, agile with mobility as their defensive midfielders........game might be running past Oriol Busquets. But if he's indeed special, he'll make the team regardless of who we sign.
