Sam's done a great job and should be allowed to do it unhindered, if the owners meddle with his strategy it'll backfire, and whilst sadly it would be Sam getting the bullet and the criticism it will be the owners fault.
i think Gary Neville made the pertinent point that owners have ideas above their station so to speak, and in modern football, with the way the elite clubs have it structured, owners of mid-table clubs have to accept that unless they really invest hard and pull in lucrative deals, that staying in the prem is the goal every season, and managers who achieve that should be respected a lot more.
Let's face it Palace would be down if it wasn't for Pulis, for the sake of their long term future he has done a remarkable job, one that, with their recent financial history, is nearly, if not as, important or meaningful to the club as winning a trophy.
Poorly run clubs go down, it's all about how clubs are run these days, you can't get away with a circus anymore. 10 years ago United could have had that transition, and really poor season (ie. Djemba-Djemba/Kleberson/Forlan era) yet still finish top 4, this season they finished 7th. You can't get away with poor management anymore.
