Not correct. An investor can pump in money but it has to be as capital, not debt, while the total wage bill still needs to remain within the permitted limit as a percentage of revenue.
The club is possibly subject to three sets of "FFP" regulations and one way or another they absolutely kill the sugar daddy model.
Premier League regulations permit up to £30m loss if covered by equity investment or £15m if funded by debt. and wage growth funded by TV revenues capped at £4m
UEFA Losses capped at 15m euro's with equity investment or just 5m euros if covered by debt there are some exceptions such as money spent on Youth development and stadium improvements but generally they are tougher than the Premier League ones.
Championship £8m loss with equity investment £3m without.
Firstly £30m lavished on any mid table team would hardly take them to the brink of the Champions League particularly if it was not backed up by wages. Even if it did the club could find it's path to European competition barred by UEFA ffp.
Secondly if relegated the club would be hamstrung by the Championship regulations which is a fate that awaits QPR.
Whoever is the Albion's new owner is I would not expect them to throw millions at the club in a vainglorious attempt to propel the club towards the upper echelons of the European game, that moment has passed. Man City and PSG were the last of the sugar daddy projects. From now on in it is serious investors with an eye on the bottom line who will be the typical Premier League Club owners.
