Marcelo Mendez gave the first list to start trainings soon. This list doesn't include any of the guys still in competition in Italy, France, Brazil, etc and also doesn't include Facundo Conte who probably will be given rest for some weeks despite the abrupt ending of season for Sada Cruzeiro. It's mostly players from argentinian league (already finished) and some from Europe that ended competition.
From these guys I think only Lima and Poglajen have any chance to make the olympic squad.
Setters: Matias Giraudo, Gaspar Bitar, Pablo Urchevich
