With his current age and the physical condition he has, he should follow Kroos. Kroos will complete his last task with the German national team at Euro 2024. Even Kroos still performs better than Ronaldo. Kroos is also only 34 years old. But his statement was quite surprising. Maybe Ronaldo and Pepe still have a great desire to play, but they have to be aware. Their condition has greatly declined. They have to start thinking about getting a license and a bear from the sidelines to become a coach. If Ronaldo still participates in the 2026 world cup, it seems that the coach will only carry the burden for other players.
Portugal actually had a pretty good performance, only since they lost 0-2 to Georgia, Portugal seems to have a deadlock on their front line, and they haven't found a goal at all in their last 3 matches. As we know, Roberto Martínez always chooses Ronaldo to be the starter in all games but it was strange to see Ronaldo not being able to score even just 1 goal (aside from penalty shootout). He is indeed old and he might no longer be as impressive as they used to be but, I don't think that's what made him fail to get a goal.
In my opinion, what prevented Ronaldo from getting goals was that he received very few passes from his teammates. Even when Ronaldo is in a good position to score a goal, his teammates seem reluctant to make an assist.
