I am not a club employee so if I'll bet against any club that's okay and that won't be against my principle.
Definitely i would bet against the team I support if they are under performing but if it involves a club I am employed to work for, I can't do that
That is one of the reasons why someone is going to bet against the club that they like. If it's going to involve your money, you either be an avid supporter and even your bets will be with them.
But if not, you're just going to bet against them when there are handicaps that you've seen on the news and that particular favorite club can't do that much for that specific match.
