They got behind Wes Morgan pretty quickly to be fair.
Most of the Leicester fans I spoke to last night (3 seperate groups unfortunately) were fairly unenthused about Cooper, but not raging. It's weird, nobody seems arsed about the current manager leaving either. They're all resigned to a huge points deduction and going back down.
I don't think he's the right appointment for them (other than the fact he's unemployed and they're brassic), I don't see why he'd be the right sort of manager for a club that will start the season as a relegation favourite. I'd be going for Moyes if I was Top.
