What makes us better?
Losing our best players makes us better!
Yay!
I know it sounds stupid, but for the last 10 years that has actually been the case.
Still, it's not a long term strategy. You can't keep selling off your star players if you want consistent success, you've got to have a core. Fellaini and Baines are the backbone of our side in terms of quality, and selling one of them would be a disaster, nevermind both.
