Juventus chief scout Renzo Castagnini has added several names to his shortlist of targets to check on during his trip to Argentina this week.

Along with long-term target Hernan Valeri, the Lanus winger, Castagnini is also Newell's Old Boys attacker Leonel Jesus Vangioni and Racing Club midfielder Franco Zuculini, who has been likened to Liverpool's Javier Mascherano.
