In the club's accounts, all transfer fees are spread initially over the length of contract. If they sign another in a couple of years, the remainder is spread over that contract, if they get sold the remaining amount is effectively subtracted from the fee received. In short, looking at the totals from any one window tells you pretty much nothing to be honest. The relevant figures are the annual amortisation of fees, the book worth of a sold player, and the amount received when a player is sold. The gross/nett spend amounts for each window, only really show a trend, not the full picture. For example, despite spending more than we received in the last 2 windows, we generated a huge profit on transfer activity, whilst carrying a much larger amount forward than normal.
