If the initial fee is 10 million, we won't actually get that much of it up front. Most transfer deals are done via amortization, so we'll probably only get 1/7th or 1/8th of the 10 million fee. Maybe even less. We couldn't really invest 3-4 million in a keeper, and 6 million on 2 new defenders because we wouldn't have the money to do so.
I suppose we could also use amortization to fund our transfers, but depending on payment structures, that may not be completely viable. Many lower end Prem clubs and EFL clubs often sharply defer their payments. They may spend 15 million on a player, pay 2.5 million over the first five years and then 12.5 million over the final 2-4 years. That's not financially viable, and I wouldn't want us to do that.
