Shit i missed a sentence in there.
I meant to say the culprit is always internal. The league when they can't afford such transfers, clubs behave responsibly like Bundesliga now.
But when they have the money, it's one club who fucks things up & starts the spending spree in the league.
Ferguson used to overpay for players like Carrick, Rooney, Ferdinand. The prices paid for them were insane for that time.
Now with Di Maria, Martial & wages to Mkhitaryan, they just keep making life difficult.
WIth Chelsea, you can tell other clubs that they have resources beyond footballing income but with United as an example, it's hard to negotiate.
