Well if you judge football without bias then obviously you don't actually support any team.
I completely understand how and why you would do this. I want us to win, and I'll take a dodgy decision for us, or against our rivals, but I know it's a dodgy decision and I'd be pissed off if the shoe was on the other foot. I'll call it out as I see it unbiased, doesnt mean i want it reversed ;)
