Martinez has explained why Ronaldo is the best player he's ever worked with, telling RTVE: "I've worked with many, but what sets Cristiano apart is the need to always be prepared to be the best. A contagious hunger, but very difficult to achieve."
The Portugal boss also looked ahead to Euro 2024 and spoke about his team's chances of lifting the trophy again.
"We have already won once. We are lucky to be able to play with four generations. Winning a European Championship has to do with the details of the day- It's a very demanding tournament, but what matters are the details," he said.
"France produces players at a volume that no other country can. England has a coach who created a club culture within the team. Belgium has a generation that is very competitive. And you can never leave out Italy, competitive for nature. And Germany, having a difficult period, but in 'their tournament' they can be champions."
