Some possible scenarios:

Chelsea – a) Roman loses interest in the club and decides to stop writing off its debt. Chelsea in theory should be the most indebted club in the world, its turnover is hugely inferior to its expenses in transfers and wages. Roman foots this bill. Should he decide to stop and have the club be self-sustaining, the spending power they posess will shrink substantially and they will go back to the position they were in a few years ago.
b) Roman loses interest and decides to sell. Unless he finds someone who is willing to cover the annual losses, a) will happen first.
c) Something happens which makes access to his money unavailable – untimely death, Putin, horrible investments apart from Chelsea a la Cragnotti – which would immediately cause Chelsea to collapse financially.

Man Utd – Due to the enormous interest payments the Glazers must make annually, because of the way they financed their takeover, any sustained lack of success will be devastating for the club. Interest payments will either eat directly into the funds available for transfers/wages, or worse yet, club assets (read: players) will have to be sold in order to meet said payments.

Liverpool – Same argument as the one made for Man Utd, but because they did not leverage themselves nearly as much (and because Liverpool was simply much cheaper to buy) I see this as less of a problem. It still exists though.

Man City – This one must be more than obvious. See Chelsea c).

And in one way or another these things can be applied to all the clubs that are in the hands of a sole owner, however rich he may be. Why? Because the club’s fate is now tied directly to the fate, or whims – call it what you wish – of one person.

Arsenal is the only truly financially healthy large club in England. They can survive, virtually unscathed, years upon years of relative underperformance.

The problem is that Roman and his staff are too concerned with now making it a brand. You hear Kenyon’s comments: a brand globally known by 2014. The best way to do this, in his opinion, is to win the Champions League twice. Roman is way too concerned with European glory, and it is now costing the Blues with the sacking of Mourinho. Notice how the Special One was gone a day after a home draw in the Champions League against a side that should have been beat.

That global Chelsea brand of business may be in existence by 2014, but the most important factor is success on the pitch, and my club has taken severe steps backwards the last couple of weeks in reaching that aim.

After what he has done to Chelsea, it is clear that he has ruined their chances at either the Premier League or the Champions League. After all you know you have done a bad job when Ken Bates accuses you of ruining a club:)
