Interesting. Munir is the best player in Juvenil A, so he is an obvious answer (if his contract issues get solved). There are a bunch of players that are 19 years old or turn 19 in the meantime so I think they must either be sold or get promoted: Maxi Rolón, Ebwelle (turns 19 in September, so might still be eligible to play for Juvenil A), Pedro Godoy, Huertas, Ortega, Godswill and Roger Riera I think. Out of these, I think Godswill is the only one "certain" of a promotion.
