Aston Villa announced this yesterday which may help gauge the sums involved, they are pretty much double the capacity although different ticket prices i guess and don't how many matches they had in various cups at home:
Match Day Revenue £24m
Commercial Revenue £14.4m
TV Revenue £52m
ps they made a loss of £37.6m and their wage bill is £80m whick worked out at 88% of turnover.
How can any club survive that kind expenditure, I run a small cafe and struggle to keep wages below 40% of turnover and just about manage to make a profit, if my accountant saw wages at that level he'd call the administrator.
