Brazil coach Tite has included Neymar in his 23-man squad for the Copa America his country will host but has yet to decide if the Paris-Saint Germain forward will retain the captaincy -- while Real Madrid's teenage forward Vinicius Junior did not make the cut.
Tottenham forward Lucas Moura and Liverpool midfielder Fabinho are among the other big-name absentees.
Manchester City striker Sergio Aguero will be part of Argentina's provisional squad for the Copa America, the Argentine Football Association (AFA) announced on Wednesday.
Aguero, who scored 21 Premier League goals in 33 appearances for Manchester City this season, had been in international exile since after last year's World Cup in Russia, when Argentina crashed out in the last 16.
The federation will submit its final 23-man selection for the tournament in two weeks.
