SCIAGSnowflake RoyalSCIAG Dai basically made two mistakes, but they're both pretty bad.
1) Put too much of his own money into the squad rather than follow the profit and sustainability rules (which would probably have led to better recruitment), ultimately forcing us to work under EFL sanctions for years on end.
2) Ran out of liquidity.
Other than that, he helped fund the training ground, he kept ticket prices at far below the market rate, and he subsidised away travel.
It's been said to death but if he sells Moore and doesn't sign Aluko and Puscas (combined with generally more sensible recruitment and retention) then we wouldn't be in this mess. Although if Dai ran out of money when we were in the Championship we'd have been in a bigger mess so maybe that's not a great line of argument.
Those small changes only swing it to about £160m lost in 6 years, from £190m. Not enough to prevent the mess, just delay it
HTH.
(But notwithstanding, we'd be much further from relegation if we had an extra £30m to pay wages and the taxman with right now)
We wouldn't though because it wasn't real money. And because if we spent it we'd get a lot more points taken off us now.
