for me i think the leavers are;

Denilson, bendtner,traore, Eboue, Rosicky, Almunia, Randall, Watt and probably a host of kids

Maybe's are Diaby, Nasri, Cesc, Arshavin, mannone, Clichy, Vela, Squidvestre

The untouchables are RvP, Walcott, Sagna, Seidcbeyajnaxzzz, Jo Djo, Gibbs, Windshear, Ramsey,

I think the rest of the squad are buyable i just dont think anyone would go after them. The one i would be said to go would be Diaby, i still genuinely feel he could be a dominant attacking midfielder if could stay fit and was coached right.
