The loan clauses Leeds had in contracts allowed the players to leave provided the loaning club covered 100% of their wages, so only their amortisation cost is on the books for this year, reducing net expenditure.
The players that left permanently all generated a book profit; and those that return can either play again next year or be sold from a position of strength as a PL team if Leeds go up.
As a result, Leeds don’t have the albatross round their neck of players on PL wages they can’t shift or significant historic losses they need to balance out with profits to comply with FFP.
Added to which they have players with significant profit-potential in Summerville and Gnonto (signed for a combined 5m) should they need to generate headroom in the event of staying down.
