You’re right, I can’t put an exact number on because none of us have access to the accounts.
However I would prefer us to go out and sign players who are ready immediately and fill specific squad gaps, rather than just accumulate prospects in the hope they come good. It’s been said by many people that the reason we haven’t been able to get those specific players is because they’re too expensive.
So, you’re right, it’s easy to say “just spend more money” but I think the money could definitely have been spent more wisely.
