Nah, Pardew's not going anywhere. Only thing that would make his position insecure is relegation but even then he's not certain to be sacked IMO. Pardew is perfect for the job in Ashley's eyes, a manager who doesn't give a fuck about the fans and happily accepts the "affordable football" model as he's overjoyed to even be managing at this level. Pardew is the anti-Keegan and that's just what Ashley wants, he's not going to find anybody more suitable.
