Well theres a lot in this, which I will try to deal with sequentially.
It doesnt really matter if BDO left, or we left them or whatever. As I keep saying, you can have as many different Accounts Teams as you wish. There is no rule against that in the rulebook.
As for the 2nd point, I would be surprised if the write downs previously are the issue, as they have previously signed off those write downs. I suspect they were unhappy with something in year 21/22 but I'm not entirely sure what.
The board, from what I can see are perfectly entitled to have write downs. It's one of these strange things football fans get irate about, but honestly this is very common outside of football, and nobody gets the least bit offended by it. I have seen accounting 100 x more dubious on income statements which is easily accepted.
Income statements, P&L etc are essentially trash beyond the top line. I have no idea who thought it a sensible idea from footballs authorities to make that the point of focus and not the balance sheet/cash flow statement. But that's football for you. Either way, the club are perfectly entitled to do write downs, and the PL accepted them, both by not charging the accounts, accepting the accounts, and re affirming that on multiple occasions subsequently.
Those write downs are a bit of a diversion really though, for the exact reason you state, which is that the P&L loss is too big even with those write downs. I'm curious as to what the clubs defence is?
There is of course legitimate questions about how stringent any punishment for what amounts to quite a narrow miss should be (it shouldn't really be more than a warning, but football is corrupt so who knows) but I cant see how they are saying they haven't broken the rules as they stand. Maybe that will become apparent to me. But the PL dont need to change their view on the write downs. That part confuses me a little.
