I am not sure all of that is entirely accurate. Equity injections are capped at the 90m but do not technically count towards PSR. But owners can guarantee that the club has sufficient operating liquidity to increase the rolling three year loss from 15m to 105m which is where the 90m comes in. Injected money can be spent on infrastructure which is excluded from PSR calculations.
West Ham made a 54m profit the season they sold Rice which is what is keeping them compliant. They made a 104m loss last season even after selling Kudus. This season they’ve sold Guilherme and Paqueta but are likely to make another significant loss anyway, not least because wages to turnover ration has increased from 54% to 77% in three years, while revenue has dropped precipitously with lower league finishes and no European football. They took a 120m five year loan of which they’ve already drawn down 90m to meet a spiralling liquidity crisis, and have nearly 200m in transfer obligations outstanding. It’s further complicated by them ending their accounting period on May 31st vs the PSR deadline of June 30th, a move nearly every other club made. Meaning they have to fact in a month of “next year’s” accounts into this year’s PSR. They are in a complete mess.
Whether any of this means they need to sell before June 30th is unlikely. I would imagine they’d have already made a big sale if that was the case. But in the bigger picture it of course means they have to sell because revenue will drop further and they are hemorraghing money on a year to year basis. They only stayed PSR compliant by selling Rice for such a massive fee. Their SCR headroom is unclear, but it will be tough based just on the wages to turnover ratio above, and turnover will drop further. Not sure how much relegation wage clauses will ameliorate that, and that’s before we’ve factored in amortised transfer costs.
As an aside, their squad cost more to put together than Bayern Munich’s.
