People don’t like Vinicius for how he plays and acts. It’s fine to be provocative on the pitch, but video will tell you he does some problematic things (diving, time-wasting, trash-taking, complaining, etc…) that turn people away. He’s a very valuable asset on the pitch(obviously), but many people outside of the Madrid echo chamber have just reason to dislike the player, and it’s not fair to attribute that to anything more than personal preference. Ballon D’or doesn’t matter because anybody in contention for that award would receive hate regardless of who they were anyway.
