Cristiano Ronaldo just scored a World Cup penalty and helped Portugal march into the Round of 16. But it's his sister who has fans talking today, not his goal. Katia Aveiro told reporters outside BMO Field in Toronto that she believes the ongoing FIFA World Cup 2026 could be her brother's last tournament in a Portugal jersey. Her comments came just hours before Ronaldo stepped onto the pitch for Portugal's knockout clash against Croatia, turning a routine pre-match buzz into a full-blown farewell watch."Enjoy It While It Lasts"Speaking ahead of Thursday night's Round of 32 fixture, Katia did not hold back. She said the 41-year-old forward's international career appears to be winding down, though she was careful to note that the goodbye is not immediate."From the information I have, he can say goodbye. Enjoy it while it lasts. It's not today that he's saying goodbye, but it's soon," Katia was quoted as saying by FotMob.She went further, framing the tournament as something fans should savour rather than take for granted."I believe this is his farewell. Enjoy it a lot. It will be difficult to find someone like him," she added, as quoted by FotMob.Clearing Up The 1,000-Goal ConfusionReporters pressed Katia on whether the retirement talk was tied to Ronaldo's pursuit of 1,000 career goals, a milestone he has been chasing across club and country. She quickly clarified that her comments were about his national team career specifically, not his overall playing days."After 1,000 goals? Yes, that's something. I'm talking about the national team. The information I have, from a reliable source, I believe this (World Cup) is his last dance," she said.Portugal vs Croatia Fifa World Cup 2026 MatchWhatever the future holds, Ronaldo made sure Thursday night was memorable on the pitch too.
