Come on Dubai .. Big difference between owner investment and simply running a club for decades as a non-viable business (and this is why it's hard to have a legitimate conversation)
Chelsea in the RA era lost £1M a week for 13 years
City has probably lost something similar if not more (hard to tell with their creative accounting)
Those are the two most successful clubs of last 15 or so years, and they have done it by spending an amount of money that if any other team tried to match (outside of United), they would have gone bankrupt
This isn't the Blackburn or even Leicester, pump some money in for a couple of years and hope for a return, this is sustained spending way beyond the revenue generated. I'd say in any other business this would be considered an unfair business practice (illegal).
Again (have to do this every time), not denying we need it to compete, but it's ridiculous to pretend football isn't fundamentally broken. And it isn't helped by media lies, e.g. City spent £56M on Haaland is widely reported, lies, they spend north of £135M with a total package of over £250M, this to a squad that walked the PL and after spending >£1B
