You can't just look at other teams budgets in terms of money, you have to factor in the success it brings surely? It's an equation.
Leeds, Derby, Villa, Brum, Wednesday, Forest spending money but they've got fuck all to show for it. We finished comfortably above Leeds, Wednesday, Brum and Forest and only 6 points behind Derby last season with a maximum transfer of ~£1million and players from the lower leagues.
Spend smart not big.
I think a lot of teams spend money to make up for a lack of staff talent. We have talented staff.
