Ronaldo is Portugal’s all-time top scorer with 130 goals in a record 208 international appearances and is playing at his sixth European Championship at the age of 39.
He moved to Al Nassr in Saudi Arabia last year but is still a fixture in his national team despite no longer being the player he was, and Martinez said that he will play in Dortmund on Saturday.
Ronaldo played all of Portugal’s opening 2-1 win over the Czech Republic in Leipzig but did not score, with Francisco Conceicao getting the decisive late goal.
He also scored seven times in seven appearances for Portugal between the season starting and the Euros beginning.
