Yakubu- sell him. He'll never find his form again.
Arteta- I wouldn't sell him for certain, but I'd consider it if we got a great offer. I know he's done a lot for us, but his form has been horrible for over a year now it seems.
Anichebe- If we got a decent offer (Unlikely)
Bily- See how he progresses until the end of the season (in which he will actually get a solid amount of playing time). If he can prove he deserves a spot here, he can stay. If not, hopefully we could get a decent amount of money for him.
Yobo- ...
Vaughan- I'd like to give Vaughan one final shot with us, and actually give him some playing time. However, if Palace or anyone else gives us a great offer, it'd be hard to say no.
Osman- NO.
Neville- I don't know, I hate the idea of losing our captain, but if he wants out and we are able to get a decent offer from Spurs, we should consider.
Distin- NO.
Heitinga- Distin is getting old and I can't imagine he will play more than 1-2 more seasons (Or if he does, not with the quality he has been playing with). Johnny is a great defender, and I think we would be glad that we kept him when Sylvain retires.
Hibbert- No. He's been a servant to Everton, and should stay here until he retires. Unless he wants out in order to obtain more playing time, then I could see him with a bottom 4th EPL side, or a solid Championship squad.
Mucha- If we get a decent offer.
