Portuguese Jorge Jesus confirmed on Friday, after being officially appointed as the new head coach of Portugal's national football team, replacing Spaniard Roberto Martinez who left his position after the round of 16 exit in the World Cup, that he will call up veteran star Cristiano Ronaldo if available, stressing that the striker 'will never be a problem'. The 41-year-old has faced criticism for his performances in the current summer World Cup under Martinez, who announced the end of his tenure with the national team following the round of 16 exit on Monday against Spain (0-1). Ronaldo had decided on his participation in the World Cup, which was his last, but he has not spoken about retiring from international football. Jesus told reporters on Friday during his official presentation: 'As long as he continues playing and has the fitness to be called up, I will call him within certain limits and under the conditions I see best for the national team.' The 71-year-old coach revealed that he has not yet spoken with Ronaldo, but they will discuss the future of the Al Nassr star in the game. He said: 'I haven't spoken with Cris yet... Cris will never be a problem for the national team. Not for the team and not for me.' He added: 'Cris is a symbol of Portuguese football... Cris is a symbol of the national team... and will remain so forever in the history books. I was very pleased to work with him over the past year at Al Nassr... He is easy to work with.' He continued: 'We will have a conversation about what he wants to do in the next phase of his career.' Jesus coached Ronaldo, the five-time Ballon d'Or winner, at Al Nassr before leaving in May after leading the team to the Saudi league title. Jesus added: 'I know that Ronaldo wants to continue playing for Al Nassr, because, as you know, I spent a year with him. He always told me that I will end my career at Al Nassr.' Jesus will lead Portugal until after the 2030 World Cup, which his country will co-host with Spain and Morocco.
