The 23-year-old is currently in the club's second team and is available on a free transfer.
Despite a shortage of first team experience the midfielder have over 40 caps for his country's Under-21 side.
Vitesse have been busy during the January transfer window having already snapped up three players as the side look to move away from the drop zone.
Pinto would be the fourth arrival should he impress on trial, following the captures of Theo Janssen, Aleksander Ilic and Paulo Rink.
