I know there will be all sorts of excuses or reasons why not, but couldn't the game be played tomorrow when the weather will be OK? All the TV equipment will already be in place, surely?
I think match day stuff makes it hard, like the security staff may have other work going on and we won’t know if we have enough staff. The catering might not be ok till tomorrow and they may not have enough time to get in more, ticketing would be hard as folk who could go today but not tomorrow, they need refunds and then you face a lot of empty seats if they can my be resold etc.
