Ronaldo to Man Utd wont ever happen anymore as a player. He is just too old and cannot give anything to Man Utd plus i dont think Man Utd want to waste money on his salaries. Also Al Nassr said that they renewed his contract for one more season and i think its over 150+ mil per season in salary for him to stay there
Why first question is why will Manchester United even want to spend a huge amount of money on a player like Ronaldo? The amount that Manchester United will be using to sign Ronaldo, it’s better they spend it on some young quality players. With Ronaldo current age, then he can’t offer Manchester United anything, Manchester United are just going be wasting money on him.
Even if Ronaldo will be joining any team right now, then the team won’t be from premier league, the team will definitely be coming from a league thats not so competitive, Ronaldo already knows that he is already getting old, and he is already getting close to retirement, so any team that Ronaldo will be playing for right now, then we should know that he won’t be going to any team that he will be stressing himself, and I guess that’s just the reason why Ronaldo is currently in Saudi pro league. They are paying him so well there, and if you can check the league, then we will see that the league is less competitive, so with Ronaldo’s current age, then he fits in there.
Ronaldo is expecting to renew is contract with Al nasser so I don't think Manchester United will try to sigh Ronaldo to the team. They need young players not at Old players. Manchester United are in a bad condition since last two seasons and they have not fixed the issue, and new season will about to begin and have not seen any big player that they have sigh to the team because seriously Manchester United need new striker in the club. But what I notice is that key players don't have the interest to come to Manchester United because they are not playing any tough competition just the league, not even in the Champions League competition.
So I observe that he will be very difficult for Manchester United to get a new key players in the team. Let see how Amorim will handle to club next season and see if they can win the EPL next season since they are not in any competition that can make them focus on both the league and other competitions but since they are playing only the EPL if they do well they'll probably be the favorite to win since they are also a big club.
