From a professional standpoint, is that something you’d want your employer to hear, or potential employers or opposition? Just feels…too honest and naive. I get that he may want to come across as more human and approachable but surely not to the extent of making himself look bad.

Yeah it isn’t right in the way he has presented it. It’s a perfectly fine thing to do in the way of “I like get the opposition and home fans engaged with me in order to focus more upon the game as the atmosphere really helps me as a player” but the way he’s presented it is wrong. “I like to muck around with the crowd because I find it hard to concentrate in a game” is the same thing presented incredibly terribly.

It’s like telling your employer at a job interview that you like to post on reddit in between tasks. Everyone does it and it might actually help you focus between work streams but you should not discuss that at all with your employer! It makes you look unprofessional.
