Problem with profitseeking ownership is 5-6bn purchase plus 1-2bninvestment in the infrastructure, an outlay between 6-8bn, if the new owners then take no money out of the club and buy no players, assuming all of our debts are cleared and we cut all the excess expenditure from our wage bill it would still take 30+ years to break even on their investment and that is assuming a manager can keep us successful without investment.
OK they would still have the value of the club but assuming that remains stable the only way they gain from it is either by leveraging debt against it or selling it on once as per the Glazers, that would probably be one of the worst long term investment plans in history. Remember that Glazers purchased utd for £790m at a time when players and their wages were a fraction of their cost now, and profit margins were much greater, it also was not their money so everything since has been pure profit for them, selling up until now has not been too tempting, clubs were not achieving such prices until Chelsea skewed the price in no small part due to the massive debt owed to Abramovich.
