European champions also revealed their preliminary squad for the 2018 World Cup.
In 2016, Fernando Santos, who led the Portuguese national team to the top of Europe, revealed the names of 35 candidates. The list does not include Renato Sanchez, who contributed significantly to the mentioned triumph.
R. Sanches, the hope of the Portuguese team, has been in his own shadow in recent years - at Bayern, the Portuguese did not receive enough playing time, and while at Swansea he shined more with actions off the field than on it.
The list includes experienced veterans such as Cristiano Ronaldo, Pepe, Bruno Alves, Joao Moutinho, and Ricardo Quaresma.
The list also includes a few young stars of the younger generation - Ruben Neves, Goncalo Guedes, Gelson Martins, and Joao Cancelo.
Portugal will compete in the group stage with Spain, Iran, and Morocco.
