**Cristiano Ronaldo, now 41, faces steep physical and selection barriers to featuring for Portugal at Euro 2028 when he would turn 43.** He confirmed the 2026 World Cup as his final tournament of that kind and has repeatedly signaled that the current club season with Al-Nassr—his contract runs until June 2027—will likely be his last in professional football. Recent comments in August 2026 reinforced plans to step away after pursuing the 1,000-goal milestone, with emphasis on family time and reduced competitive load. While Ronaldo remains available for Portugal under new coach Jorge Jesus and was named in the latest Nations League squad, historical patterns show few outfield players sustain elite international output into their early 40s. Portugal’s squad is also evolving toward younger talent, and the demands of a major tournament at that age introduce significant injury and form risks that traders weigh heavily against participation.
