Football profit index(Image: Peter Byrne - PA Wire)

As another busy football transfer window draws to a close, fans at both ends of the spectrum have had plentiful reminders of the huge spending required to succeed in the modern game.

What only very few people seem to be asking, though, is "what's in it for the owners?" After all, on-the-field success doesn't often produce a big enough profit to cover wages and other expenditure.

With the likes of Manchester City, Liverpool, Manchester United and Chelsea all spending big again this year - and with those all important Financial Fair Play rules soon coming into effect - here are my views on each club's chances of making a profit in the near future.
