Surely the incentive for buying a football club comes from the increase in value that will come with the TV deals. I think it's predicted that the foreign TV deals will get more and more valuable, and that is what is driving most of the investment. If you can make a club a mainstay in the premier league, and turn it into a global brand by playing in the CL, then you could have an asset worth £1bn plus in 10 years. Maybe even a perennial midtable club could end up being worth that. Look at Man City, for all the money they've spent the club is now worth $3bn, they've been a great investment.
