And when you're not bothered about even trying to compete for those metal pots, don't be surprised when supporters stop spending ridiculous amounts of money to watch 11 men run around a field on TV or at the stadium every weekend and the revenue for your business starts declining.
The business of Manchester United won't keep making money forever as the football team gets worse and worse. The business exists because of the football, not in spite of it.
They will not be surprised, but they will not spend disproportionately more either (correctly). They will either cut cloth as a lot of people with a business do, infuriating fans further and/or sell up, for the whole cycle to begin again.
I don't envy club owners, and I do not know why anyone would want to own a large club. Football fans act like it's monopoly money. Absolutely ridiculous.
While I'm at it, having an owner come in, spend huge amounts of money and then be hounded out for someone else when they are no longer willing to do it,
is exactly the same as having one owner come in and spend huge amounts of money for many years.
The reality is there are only
two types of owners: Sugar daddies and businessmen/women who are in it to make money, which is the point of business. Some truly care about the club and will make allowances to make a little less money, but those are rare. You are deriding the Glazers for being businessmen, which simply means you are after a sugar daddy. Except that is unconscionable for you so you pretend otherwise.
Finally, having an owner bankroll a few huge spending sprees, then being hounded out when no longer willing to do it, so another person/people can do the same, then another person ad infinitum is essentially sugar-daddyism anyway, so if people here want that, you're still no different to City fans.
