I hope you are aware that the general consensus is that Russian billionaire and Sheikh owners are destroying football? The Agnelli's have done a lot more for Juventus than just putting in money. A club's identity comes from tradition, but has to be enforced by the current owners. Selling the team's identity for short-term success would be ridiculous.
We are moving towards a situation where Champions League football is like FIFA 2011, the only thing different between teams is their colors. It's nice for Chelsea fans that they've had so much success over the past eight years, but they are now supporting a club that is owned by a guy who considers it as a toy, and who has never seen a Chelsea match before he bought the club.
