I’m still planning on going.Same. I'd rather miss it than have to tell the Mrs that Christmas with the family is cancelled because I caught Covid at a football match. Just not worth the risk.
TBH I’m more likely to catch it from my primary school age grandchildren, one son who is a paramedic, the other son who is a police officer and his wife who is an NHS counsellor. We’ve seen them all in the past week and they will all be at mine on Xmas day.
Getting within a few yards of you lot for a couple of hours is the least of my problems.
