In fact, at the age of 38, he is still in demand by many clubs. In fact, many big clubs want to bring Cristiano Ronaldo from Manchester United. It proves that Ronaldo's quality is still maintained even though he is old.
As you said, that Ronaldo is the top goalscorer at Manchester United, it's one of the proofs that he can still compete.
But even so until now there is still no certainty which team will sign Ronaldo, many teams are being linked with Ronaldo now but it's just a rumour. So yes, Ronaldo does have its own charm but unfortunately, his old age and too high a salary make teams who want to sign him will certainly consider him again. But if these teams really need a player who has a good influence to motivate the team even more so to help him win the Champions League title next season, then Ronaldo is the right player but if they consider for the long term then Ronaldo is not the right choice.
He is one of the phenomenal football players at the moment so it is only natural that he is quite in demand even though he is not young anymore.
But it is certain that there are some obstacles, such as the salary that is quite large that must be spent for this player, although this is actually quite worth it with what he brings in terms of sponsorship and in terms of marketing, it is clear that he is one of the most profitable for the club.
Now it is only about who is ready to spend money then indeed he has a greater chance of bringing in this player.
