This is being driven by the American owners of Liverpool and Arsenal. They want to achieve the highest return on their investment. They think, Liverpool particularly, that they can find the best talent at the cheapest price. ie moneyball. If possible with no jeopardy ie no promotion or relegation. United and Chelsea want the same thing but they are not in position at the moment. Chelsea abstained because they are buying time and don't know which way is up at the moment.
They do not care about trophy's. They care about guaranteed returns.
And they lead the other American owners in the vote to! Parish at palace who sold stake to American owners he does there bidding
