He won't get many chances to go elsewhere obviously Where should he actually go? Must be a club with a lot money, but who really wants him for next or even the season after next one?
He is now 36 years old and I think he should now stay at Manchester United while enjoying his old age at this time.
In terms of performance, he is still quite good but even so he must be able to see from the other side like his current age even though it may not really apply to him.
He definitely does not go back to Juventus. The question is just where is he going when he decides to leave ManU? There isn't really a place for him currently. He won't go back to Juve, Madrid definitely no option, especially because players like Mbappe and Haaland are the future. Where else could he go? I can't think of a club where it would make sense now for both sides, financially and also in terms of the quality Ronaldo brings to the table. Germany is no option, Italy seems like no option, France also not I guess, so? He might play for Manchester United for two more seasons and then go to the United States.
