Fernando Santos's side, who are the holders of the trophy, having beaten France 1-0 in the final five years ago, will have a number of familiar names in their starting side for this contest.
However, they will be without the services of Joao Cancelo, who has tested positive for coronavirus and been replaced in the squad by Diogo Dalot, meaning that Nelson Semedo could feature at right-back for this match.
Cristiano Ronaldo, of course, is also a guaranteed starter, but there is some uncertainty surrounding the left-back spot, where the excellent teenage defender Nuno Mendes is providing competition for Raphael Guerreiro.
Ronaldo will enter the match having scored 104 goals in 175 appearances at international level, and it will be fascinating to see how the 36-year-old performs at Euro 2020.
Portugal possible starting lineup: PatrIcio; Semedo, Dias, Pepe, Guerreiro; Danilo, W Carvalho, Fernandes; Bernardo, Ronaldo, Jota
