C Ronaldo or Messi, if it was five or eight years ago, would the team sell them? If the team decides to sell them, the free market will obviously be crazy, but now? I can't lift any water.
Messi is sober. He accepted the fact that his condition was declining. He was not the core of the team, but Mbappé's "assistant". So, Messi has been at home in Paris. Although there are few goals, there are enough assists.
And C Ronaldo? He doesn't accept the fact that his state is not as good as before, and he still insists on being the core of the team. Perhaps he is limited by his physical fitness and the habit he has developed for so many years, and he is not qualified as a midfielder and organizer like Messi. He can only be a striker, so combined with Ronaldo's strong personality all his life, he can't accept being the second or even third attacker of the team.
Although the decline in the performance of Juventus and Manchester United is a problem of the overall strength and configuration of the team, is there any reason for Cristiano Ronaldo? The answer is definitely yes.
