First and foremost fantastic performance.
Potential reasons for lowish crowd:
Fear of virus.....rates increasing again...many fans of a certain age
Cost..not only price high (the kids issue was probably an error) but more importantly many have been hit very hard over last 9 months.....and it's an expensive time- Christmas coming up
Cold, wet day
Possible assumption that it might be another heavy defeat to a top side
Match viewable on stream...a much cheaper warmer, safer option
