Brother no rational person denies that Cristiano is an amazing player and has achieved everything in the game & in life.
The hatred stems from his behavior.
He's 41 years old and acts like a spoiled brat and is a narcissist.
Yup! He's one of the GOATs. No doubt about it. Have seen him play during his prime and he was a beast. Mbappe and Haaland don't come close to what Ronaldo was capable of.
I don't elevate him to the level of Messi because Messi is complete player and in my eyes a complete player is always better.
But it's Ronaldo's behaviour especially in last 8 to 10 years which makes him so unlikeable to me. He's narcissistic and lives on "Planet Me" and I am not a fan of such behaviour.
People can turn blind eye to such narcissism but I can't.
And, at the same time, it's also true that Ronaldo in last 7 years had been just a shadow of his former self and burden of failure of Portugal falls on his shoulders the most - and not on other teammates (they are responsible as well but not as much as Ronaldo as he's also the captain, has most say in team management, and a leader)
People can appreciate him for his skills while acknowledging that he's the one who's responsible for ruining his own legacy and Portugal struggles due to his own behaviour
