If he gets another chance and impresses against West Brom then I can easily see him making their 25 for next season with a new deal, and who could blame him for staying. It'll boil down to whether he believes (or is told) he can regularly make the bench and progress from there.
No, it will boil down to how much of the £35m Ashley has promised Pardew can spend, he actually produces.
If they re-sign N'zogbia (insert alternitive here), that will leave KLL as at least FOURTH choice behind Ban Arfa, N'Zogbia and Gutierrez.
