That's just stupid. A lot of male athletes get criticized and disliked for being too arrogant and cocky.This is just a latent form of sexism, IMO. If a male tennis player says "I work hard and expected this win from myself", like Dimitrov did yesterday, no one bats an eyelash. He's just being a regular "confident" guy.
But a woman saying the same thing? Suddenly she's conceited and arrogant. Society still expects women to be modest dolls who just sit there and look pretty.
One of these days even taking a shit will be regarded as sexist. Jeez.
