Manchester United captain Bruno Fernandes says he doesn't take his place in Portugal's squad for granted.
Fernandes admits he has ambitions of playing well into his 30s.
"A place [in the squad] is getting more and more expensive. Increasingly, clubs are investing in youth teams, so that more players come [to the national team]," he said.
"At that time [of the 2030 World Cup] it will be even more expensive, but, if I'm fit, and I'm at a level that is the minimum acceptable to be here, I hope to be here.
"Representing the national team in a major competition and in the country itself is very special. I hope to be present."
