Or they just have better negociators than MU and many many, other clubs in the world.
And they got a plan. Not saying that they don't have many skeletons in their closet, they absolutely have, but this just sounds like sour grapes. There's currently no real reason for him to chose MU, or any other PL top club for that matter, over Man City. They sold Palmer who never had a real chance under Guardiola and never would have, to buy a player more suited to their system. System being the key word here. Palmer will do well elsewhere, imo. People might (rightly, most of the time) object to Man City's dealings, but they buy and sell smart. Furthermore, from a player point of view, it's just a no-brainer, especially with them now breaking that perennial CL mental block. They now have a bit more than just the financial pull.
No aiming at you personally, but I get the feeling that too many people are letting their bias getting in the way of facts.
