The situation is fairly clear. Donald overpaid for the club and no one is going to pay enough for him to breakeven whilst SAFC is in League One.
The FPP deal gives Donald a chance to get SAFC promoted at which point, FPP will pay enough for him to get out without a big loss.
But FPP can’t force the timeframe. Donald doesn’t have to sell unless he wants to. But he has zero interest in putting any more money into the club. That is why he took the loan from FPP. SAFC runs at a loss so if it was not for the loan, he would have to finance that himself. He could do it, he just doesn’t want to. So his comments about how he could pay it back or put it in himself are a half-truth. He doesn’t want to take any more risk. He is already down £10m by my estimate. He doesn’t want that to be £20m.
If SAFC don’t go up this season, then unfortunately there might be enough wiggle room for SD to have one more go at it next season. But then he is definitely out of time and FPP takeover.
Either way, FPP end up owning the club. Next season in the Championship or later on still in League One. The only uncertainty is price - which is dependent on which division the club is in at the time.
In the meantime, SD will of course be desperately looking for someone to buy the club off him for more than £35m. But £10m of that goes to FPP and £25m goes back to SAFC to repay the parachute payments. So the big question is what does SD do if he gets an offer of £35m from someone less good than FPP? My guess is he will take it and get out. Luckily, I doubt anyone would be mad enough to pay that.
