Reinier is one of the inscribed by the club in the Libertadores, although this year has not yet done activities in the field with the professional team. Even if it were sold now, the midfielder would remain on the team until he turned 18 in January next year. His contract with Rubro-Negro is until December 31, 2020. If he does not sign the deal, the board intends to renew the bond until 2024 so he will not risk losing it for free in the middle of next season.
