It can lead to issues though, although not as obvious as betitng to lose e.g. If someone is known to regularly betting on a side to win, then they dont bet on a particular game, this sends out a signal to the team and maybe others which might impact confidence etc. As someone else said it could lead to bribes if debts are run up etc.I don't see why betting your own team to win is such a bad thing, providing you're not betting on specific scores or number of goals.Obviously, it's against the rules and they shouldn't be doing it but it would, surely, influence them in a positive way, unlike betting against your own team.
