It hasn't always kicked off. More so than never, though.
There will always be scuffles as fans cross each other, especially at OT. There will be a lot of bouncing around and chanting outside the ground after the final whistle until GMP deploy their attack Dogs and disperse the fans.
But, an early kick off substantially reduces the risk of crowd trouble inside and outside the ground.
We all know that local derbys, no matter which city they are played in around the World will always result in flash points and trouble.
But again, I go.back to a ridiculous 5.30pm.kick off on a Saturday night, with all day drinking.
The TV companies, City and United, and GMP knew what was going to happen. We all did. But they let it go ahead.
They are just as much to blame as the fans who misbehaved on the night at the Etihad.
