Have we ever sold a player against Moyes or Martinez's wishes? Doubt it mate. It's the one good thing that Bill makes sure happens. Moyes might have had to have sold to buy at times, but who he sold, who he bought, and how he managed HIS budget was always up to him.
I always remember when we sold Arteta and we did not have time to get any deals sorted..... Stop laughing people. A few months later Moyes admitted the money went to the bank.

Looking back at his words, you could see his heart was not in it anymore. He was well paid and accepted the lack of support and backing to buy new players.
Just hope Martinez does not end up the same way.
