Play decent winning football and he wont be.
I still don't think the level of performance/style of football has any bearing on whether he's sacked or not. Hughton wasn't sacked for footballing reasons, and Pardew wasn't kept for footballing reasons. Hughton just wasn't compatible with the set-up.
Providing Pardew remains compatible (ie, doesn't kick off with Kinnear/Carr/the owners), and we're above the relegation zone, he'll see out his contract.
Please. No.
