I guess betting against Latics is just not for you, I've been betting against us for years and have done pretty well doing so as well.
I particularly remember a midweek match a good few years ago, we were at home to Leeds. I saw the teamsheets and thought bloody hell we are going to get mullered here, we had a few injuries and Paul Black was playing at left back (which speaks volumes for the strength of the Latics team that night). I went to the bookmaker at the back of the main stand and asked for a price on Leeds, they were 8/11, I thought that was buying money, I had a bout £120 on me and quickly put it all on.
We lost the game 2-0 and never threatened the Leeds goal, I left the ground that night and although disappointed we had lost, I collected my money and didn't feel atall disloyal or that I had betrayed the club.
We were going to lose with or without my bet, I just took the opportunity of profiting from the loss.
I've also on occasions backed us to lose and we have either drawn or won, that's the gamble, I don't see why anyone should get bent out of shape just because they've predicted Latics to lose, we do lose quite often.
