No, its much more straightforward than the winning of titles. You need to follow the money...
The important thing with regards to the money is qualification for the Champions League. Once you're there. you earn significantly greater income (and profit) by extra TV, commercial deals, matchday income etc. In England, it was all very nice - three spots for Liverpool, Man U and Arsenal. Then along come Chelsea and miraculously a fourth spot opens up. Then along comes City and...oh, wait a minute. the existing teams can't simply guarantee qualifying each year. Even more problematic with Newcastle threatening to join the party....
So actually who wins is irrelevant, just being in the room's the key to this. So, stop the new guys becoming good enough, and as a side issue relieve the pressure on the existing teams actually ahving to spend to keep up...
