Cristiano Ronaldo is already 40 years old, he is not young anymore and I think he has many reasons for his decision and the most reasonable one is that he maintains his fitness to stay fit and maintained for his target of playing in the 2026 World Cup in a fit condition.
Well, I see that many people say that he's old, that he's finished , but did you see how he Retired Imaine Yamal? What's the point of being so young if you don't have Experience? CR7 is perhaps in better physical shape than him; he got injured and still scores goals I will always assume that age is just a number, and it's a given that he'll be in the World Cup leading Portugal.
