I think the problem is that there's been no transparency about what the actual FFP issues are.
Premier League FFP rules state you can lose up to £105m over a rolling three-year period. However, any losses incurred between £15-105 million must be covered by the owners. Next season, the club will have to account for this season, 20/21, and 21/22. In 20/21, the club made a profit of £18.4m. In 21/22, the club made a loss of £46.1m. This season will likely be losses of a similar amount to last season or even slightly higher, so that profit in 20/21 is especially important in keeping us below the permitted £105m.
The problem will be in a couple of seasons, in that 2024/25 FFP assessment period that will take into account the last three years, it won't include that 20/21 season where the club made a significant profit. It will take the losses of 21/22 (-£46.1m), 22/23 (likely -£50m~), and 23/24. That's where this summer comes into play. If we project the club are operating with over £90m of losses over the last two seasons, it puts a squeeze on 23/24 to avoid going over the permitted figure of £105m.
I believe that's what the real issue is. Our net spend cannot feasibly be over £100m as it was this season.
