Even in the dark days of the atrocious slow football under Garcia and Hyppia, with TB reigning squad spending in, s/t sales only fell by 3,500 I think. So there's a huge loyal base who keep their seat come rain or shine. This season perhaps there'll be empty seats against non 'glamour' clubs...
Parachute money:
£48m 2018/19
£37m 2019/20
£17m 2020/21
Bear in mind that the Albion were running £26m or more annual losses in the Championship and would now have PL scale wages on their books.
