If he is willing to accept a salary that is not too big then there is a possibility that a European team will sign him, but if he asks for a high fee it will certainly be quite difficult for a team in Europe to re-sign him. Several teams that will compete in the Club World Cup have a short-term interest in signing Ronaldo such as PSG and Real Madrid,
Signing ronaldo wouldn't have a huge advantage for the playing pattern. But I think the team will think in terms of business. If the team's target is to lift the team's performance I think it's not a good move. I think it is better to sign a player with potential at the same price than Ronaldo. His age and ball control are far away for European competition I don't think he can compete to play fast and high tempo.
Obviously, age has ran out of him and we all know that football is one of those careers that regardless of your level of experience in the game, once you're no longer fit, it starts to show too evidently in all your games. With regards Ronaldo's ball control and general play, he's still goated till this day, What's just lacking is the fitness and that's why he can't play for any European team because his fitness will be found wanting at moment that matters the most.
As much as most fans wish that he keeps playing, the reality is ghG he's paid his dues and now, it's time to say goodbye to the game or to play at a smaller team where he won't face serious issues and won't be compelled to over work like what's certainly going to be the case if he's to play for a European team.
I've read in research articles that Ronaldo's body is younger than his age. But I don't think that's true, we've seen how his speed, technique, and ball control have been much different. He's not as good as he was at his age in the study.
His body being younger than his age doesn't mean that he's going to be performing like he used to at the time of his prime. If you consider the number of goals he's still scoring even at this age considering that he's playing against young stars, it's enough to let you know that with his age, he's still playing like age is still on his side.
How many of those in his age bracket that played together with him are still as active as he currently his now? That's the thing na, he's aging and that's for a fact but he's still not doing bad considering his age..
