I shudder to think. Just look at the players we bought but gave away/sold for a nominal fee:
A Williams £12 mill
M Schneiderlin £25 mill
Y Bolasie £27 mill
G Sigurrdson £45 mill
S Ramirez £5 mill
T Walcott £25 mill
C Tosun £27 mill
Y Mina £27 mill
J Gbamin £25 mill
F Delph £9 mill
A Gomes £25 mill
M Keane (almost certainly) £30 mill
Not including the huge financial hits on Allan, Klassen and Godfrey.
The problem was never spending too much money (it’s about what our club should be spending), it was wasting it on players we recouped nothing from.
