Ronaldo opted against retiring from international football after Portugal suffered a surprise exit at the hands of Morocco at the 2022 World Cup, remaining an integral part of the Selecao setup under Martinez. 

His 14 European Championship goals are an all-time tournament record, putting him five clear of Michel Platini, and he will look to widen that gap in Germany this year.

Portugal, who won all 10 of their qualifiers while scoring 36 goals, will open their Group F campaign against the Czech Republic before facing Turkey and Georgia. 

There are few surprises in Martinez's squad overall, with Manchester City's Matheus Nunes and fellow midfielder Renato Sanches among the most notable absentees.

Bayern Munich's Raphael Guerreiro is absent after missing the end of the Bundesliga campaign through injury, but Wolves winger Pedro Neto is included despite only returning from a hamstring issue on the final day of the Premier League season.

He is one of 10 players from England's top flight to receive the call-up, with Manchester United's Bruno Fernandes and City star Bernardo Silva among the biggest names to make the cut. 

Unlike England boss Gareth Southgate, Martinez opted against naming an expanded squad and cutting it down to 26 closer to the tournament, so his final party will take on Finland, Croatia and the Republic of Ireland in warm-up friendlies next month. 

Full 26-man squad: Diogo Costa (Porto), Jose Sa (Wolves), Rui Patricio (Roma), Antonio Silva (Benfica), Danilo Pereira (Paris Saint-Germain), Diogo Dalot (Manchester United), Goncalo Inacio (Sporting CP), Joao Cancelo (Barcelona), Nelson Semedo (Wolves), Nuno Mendes (Paris Saint-Germain), Pepe (Porto), Ruben Dias (Manchester City), Bruno Fernandes (Manchester United), Joao Neves (Benfica), Joao Palhinha (Fulham), Otavio Monteiro (Al-Nassr), Ruben Neves (Al-Hilal), Vitinha (Paris Saint-Germain), Bernardo Silva (Manchester City), Cristiano Ronaldo (Al-Nassr), Diogo Jota (Liverpool), Francisco Conceicao (Porto), Goncalo Ramos (Paris Saint-Germain), Joao Felix (Barcelona), Pedro Neto (Wolves), Rafael Leao (Milan).
