Cristiano Ronaldo says he will retire after Euro 2024.

Cristiano Ronaldo declared with certainty that his remarkable career will end "without a doubt" at the European Championship in Germany.

Ronaldo will make a record-breaking sixth appearance at the European Championship in 2024.

In four years, when Ronaldo will be forty-three, the United Kingdom and the Republic of Ireland will host the following tournament.

"It's the last Euro [for me], without a doubt," Ronaldo stated to RTP on Portugal TV.

"But that doesn't make me feel anything. It's not about quitting the world of football; it's about the passion of people, the game, my family, and everything that comes with it. I find myself moved by everything that football includes. What more can I accomplish or succeed at?"

Ronaldo, who won the 2016 tournament and made his Portugal debut in 2003, is the men's all-time top scorer with 130 goals.

"The most important thing about the journey I've been on is the enthusiasm I still have for being here," he stated.

"It's 20 years representing and playing with the national team, bringing joy to people, to the family, my children, that is what motivates me most."

On Monday, Ronaldo's mental toughness was put to the test as Slovenian goalie Jan Oblak saved his penalty kick in the 114th minute.

Portugal defeated Slovenia in a penalty shootout, with Portuguese goalie Diogo Costa stopping all three of Slovenia's attempts to win the round of sixteen match.

When the match entered a penalty shootout, the superstar from Al Nassr started crying and needed his teammates to comfort him.

"It's football; those who fail are those who try, too," Ronaldo stated. "Regardless of whether I succeed or fail, I will always give this garment my all.

As you can see, I missed the penalty, but I still wanted to score first in the penalty shootout because you have to step up and take charge when the team needs it. You shouldn't be scared because I've never shied away from taking on challenges head-on. I may not always succeed, but I'll never tell you to give up."

With 14 goals, Ronaldo holds the record for most goals scored in the competition's history, but he has not yet found the back of the net in Germany.

The five-time Ballon d'Or winner remarked, "Obviously it's frustrating when we can't score, but it's football."

"The most crucial factor was that the outcome was favorable in the end.

"I've lost on penalties twice this year—against Al Hilal in the King Cup of Champions final and to Al Ain in a penalty shootout in the Asian Champions League quarterfinals—but I just won today.

"I think football sometimes has to be fair, and it was fair because I think Portugal deserved to win."

Portugal will now play France on Friday in the quarterfinals.

"We will now have a difficult game against France, who are the favourites to win the competition along with Germany and Spain," Ronaldo stated.

"But this is football, we're going to fight. The team is performing well; the victory over Slovenia gave us more energy, and we will battle to the very finish."
