Advice needed for tonight's game!

I usually get a lift with someone with parking at the stadium. But this evening I'm picking up my daughter from footie training and going straight in, probably not arriving until around kick off.

Am I right that the stadium car park closes 30 mins before kick off. If so, are there any other options which don't involve a 20 minute walk! From memory, the Asda retail site car park hands out fines, so think that's a no go!
