Or you could sugar daddy a club, win a record seven League of Wales titles, get bored, pull the plug and the club goes bust. Twice. That's the Barry Town story.
Or, you could sugar daddy a club and threaten to pull the plug. Oxford and Derby know this all too well thanks to a Mr. Ian Robert Maxwell. And clubs like Middlesborough and Bristol City would be nowhere without the resources and patience of Steve Gibson and Steve Lansdown respectively.
Or, you could sugar daddy a team, get bored, sack your manager and hire three more managers within twelve months. That's the Wolverhampton Wanderers story.
Or, you could sugar daddy a team, spend way too much on a bunch of mercenaries, sack the man who got you promoted, sack his successor, then hire a crook. That's the Big Book Of Queen's Park Rangers.
Or, you could sugar daddy a team, do well and still sack the manager. But replace him with someone who doesn't do that badly. That's the legend of Southampton FC.
Or, you could sugar daddy a team, secure the club's assets against the bank you also own, and then cry when that bank goes bust and the debtors come knocking, saying that they're taking over your stadium as collateral. That's how Heart of Midlothian have had it this year.
Being a sugar daddy isn't easy. For every Chelsea and Manchester City, there's an equal and opposite Gretna.
