Cristiano Ronaldo is set to start for Portugal in their Euro 2024 opener against the Czech Republic, marking his record-extending sixth appearance at the European Championships. Despite initial skepticism, new manager Roberto Martinez has successfully integrated Ronaldo into the team while maintaining a balanced squad. Portugal qualified for the tournament with a perfect record, scoring 36 goals and conceding only two, and aims to win another major international trophy after their 2016 triumph. Czech legend Karel Poborsky believes that Ronaldo's age could benefit the Czech team, while Ronaldo himself is open to being benched if it benefits the team. The match against the Czech Republic will be a challenging start, yet Martinez praises Ronaldo's commitment and leadership. Ronaldo aims to enjoy the tournament and potentially become the oldest goalscorer in Euros history.
