Cristiano Ronaldo says he has done his duty for Portugal after helping them to win the Nations League on Sunday.

Portugal came from behind twice in normal time to earn a 2-2 draw against Spain before earning a 5-3 win in the penalty shootout to lift the trophy for the second time.

Nuno Mendes and Ronaldo cancelled out Martin Zubimendi and Mikel Oyarzabal's efforts, but Diogo Costa proved the hero during penalties as he saved Alvaro Morata's spot-kick before Ruben Neves scored the winner.

Ronaldo's strike, his 138th for his country, proved crucial in the context of the game. Indeed, no player has scored more goals against Spain than him in all competitions since January 2004 (Eduardo Vargas also has four).

The five-time Ballon d'Or winner was in tears after the final whistle, having claimed his third international triumph, following on from his 2016 European Championship and the 2019 Nations League.

"What a joy," Ronaldo told Sport TV. "First of all, for this generation, which deserved a title of this magnitude, for our families. My children came here, my wife, my brother, my friends.

"Winning for Portugal is always special. I have many titles with clubs, but nothing is better than winning for Portugal. It's tears. It's duty done and a lot of joy.

"When you talk about Portugal, it is always a special feeling. Being captain of this generation is a source of pride. Winning a title is always the pinnacle in a national team."

Portugal have now become the most successful team in the history of the Nations League after lifting their second title, and their first since 2018-19.

This is the first international trophy for Roberto Martinez, after failing to win anything while in charge of Belgium.

Martinez has come under pressure in recent months, with rumours suggesting his job could be on the line.

The 51-year-old said this trophy was not going to be used as a way to answer the doubters.

"No, I have been a coach for many years. I started in 2007, I had the opportunity to play more than 100 games with national teams, and the most important thing is what the group of players feel and the commitment we have every day, apart from the noise that is part of football," he said.

"Sometimes criticism is healthy and good, other times it is malicious and has an agenda, so for me, the pride of winning the cup for our fans is a satisfaction. [They] made an incredible effort when we needed it most."
