As far as I'm aware there are no penalties or sanctions in the Premier League for match postponement. There are standards all clubs are expected to match. Personally I can't see how any club can be sanctioned for a weather event. There's a huge difference between a pitch being able to drain anticipated rainfall levels and a sudden deluge.
I thought there were...but I cant find it in the 80 page Premier League rules document
but when was the last time a Premier League game got cancelled for a waterlogged or frozen pitch... #justsaying
