Oh dear.
I know you'll be hurting tonight, but that sort of shit really annoys me.
In 2007 we had a dinosaur in charge, just been beaten 5-1 in a final by your team, and were going nowhere fast. The next few years were more of the same, but I and most other proper supporters never turned their back on our club.
Personally, instead of making daft threats like the above, how about put some effort into persuading your chairman to actually invest some of the money he's made from the club over the years into the playing squad?
