When people have too much self-confidence, it becomes either funny or annoying. In soccer there are great examples of both.
In the US you guys had Zlatan Ibrahimovic running around for a while. Too much self-confidence on the pitch, clearly demonstrated by his goals, but also outside. Many examples of cocky but funny interviews, like the one at Jimmy Kimmel, and witty comments. It’s probably both an act and the way the player really is, but it is funny, and, most important, it works. Everybody loves the guy. Aaron Judge could be this man, although he isn’t really arrogant.
