Do the big teams at this time no longer see the age of players like Ronaldo who are already in the old category? so you think that the big teams will send a proposal to Manchester United in terms of buying Ronaldo. A large salary is indeed a barrier for some clubs who want to bring Ronaldo, but Ronaldo's age is also a barrier for big teams to send proposals to Manchester United.
Ronaldo age is not a big problem for clubs interested in signing him in this summer's transfer window. The proof of Ronaldo age is not debatable because he can still make a big contribution to the team as last season he was the top scorer in the Manchester United squad. even his arrival can increase the club income from the sales of merchandise and other accessories. Bayern may be the best choice for Ronaldo besides PSG because these two leagues have not been tried by Ronaldo during his career.
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.
