They are still good players who will need to be replaced.
Sure its not the end of the world if a "squad" player wants to leave but its not just them is it? There's a lot better players who seemingly want out.
They do need replacing, I agree with that. But you really can't expect youngsters like Gosling and Anichebe to stay content with a place on the bench or a run out with the reserves. They have to play regular and as said, they have about zero chance to get that with us. They have far too many good players ahead of them.
The other ones who want out?
Pienaar, it's all about the money. We either not prepared to, or can't afford the wages he's after. It's a shame he's leaving, but I completely understand the clubs policy on this.
Heitinga, think he believes his own hype far too much. I know Moyes promised to use him as a CB, but he can't expect, to get that spot without competing for it. He wasn't first choice at athletico and now he's not capable of getting in the Everton team. Self criticism in a largely unknown territory for most footy players these days.
The other ones Yakubu, I guess? Was playing alright, before being dropped, but didn't deliver the goals. Think it's time for a major reshuffle in the strikers department. Would only keep Beckford and Vaughan.
