Argentina coach Gerardo Martino on Thursday named part of his squad for the Rio Olympics but superstar Lionel Messi was not included after being chosen for the Copa America instead.

The full list of 22 will be revealed in the coming days but not before Sunday's final of the Copa, where Argentina take on holders Chile.

Messi's exclusion was expected. He won gold at the Beijing Olympics in 2008 but Martino had already decided that the Barcelona star would not compete at both the Copa and the Olympics in August.

Nine players were named in the squad on Thursday.

They were Giovani Lo Celso (Rosario Central), Geronimo Rulli (Real Sociedad), Angel Correa (Atletico Madrid), Emmanuel Mammana (River Plate), Jonathan Silva (Boca Juniors), José Luis Gomez (Lanus), Mauricio Martinez (Union), Leandro Paredes (Empoli) and Cristian Espinoza (Huracan).
