What are you talking about? Narcissistic people are universally disliked, Ronaldo is that guy, Messi is not. I have not heard Messi making toxic statements, interviews about his ex-teammates (imaging Messi saying Xavi, Iniesta etc. is jealous of him in an interview), criticizing his teams, disrespecting the coaches, managers etc. I have not heard Messi regularly making statements like "I am the GOAT.. I am the best .. I have 4-5 Ballon Dors, Xavi none..."" etc. etc. type of childish statements either.. Also, it's beyond me how you can call yourself a United fan seeing the way Ronaldo treated your team since the beginning of summer (like a garbage), most United fans here seem to have enough self-respect and pride to put him in his place..
Many people dislike Ronaldo and his fans portraying him as a GOAT despite all his limitations, limited technique etc. thanks to the power of social media. This is something I have been saying for years, now the whole world seems to agree with me (even many of his fans) and loves making fun of him.
If someone ever finds himself in a situation where everybody seems to dislike/hate him (even the fans of the club where he was made, United), then he has to take a break in Swiss Alps and somewhere similar with tranquility, read Meditations by Marcus Aurelius and then maybe he will transform. Though judging by his Saudi contract video, the guy seems helpless and seems to have no intention of getting therapy to deal with his narcissistic traits..
