Everyone answered the question so I'm not going to repeat others' sentences. It's just shame Ronaldo can't somehow control his ego and realise that he's been amazing for 15+ years, in top 5 of best football players of all time (even the GOAT for many) and not he's almost 38 and it would be incredible to keep up the same level. He's obsessed about being the best which is admirable but that obsession could hurt him now.
I think that’s ultimately why he’s been so successful. He clearly has that drive, arrogance and self-centred approach to want to be the absolute best. But not only be the best, he wants the world to tell him he’s the best. I think we’ve seen hints of it before in interviews related to Ballon D’ors and comparisons to Messi. He’s always been touchy about it.
Those attributes have been a factor in pushing him to reach the extraordinary levels that he has done. It’s also allowed teammates, fans and managers to turn a blind eye to all the negative aspects of his personality because let’s be honest, most l people are tolerant to anything as long as they have the superstar fighting in their corner.
The major problem arises when he’s no longer capable of performing at those levels to the point where he actually becomes a liability in the team but he still has the attitude and ego he had before. It’s a recipe for disaster where everything that was tolerated before will now be banished and punished as there’s no downside to getting on his wrong side.
It’s unfortunate to see, but he’s already showing signs of potentially struggling with the lack of limelight and attention he will get once he finishes football. I wouldn’t be surprised if he makes a terrible attempt of trying to go into something like acting to massage his ego.
