I think sacking Powell now would be the biggest mistake this club could make since the appointment of Dowie.
We're a demoralised side filled with injuries, but we're not in the relegation zone, and our players (in my opinion) have the ability to turn results around and push us up the table. Sacking Powell would send us on a downward slope. I'd hazard a guess at around 90% of players in our squad who feel a sense of loyalty to Sir Chris for either giving them a chance to prove themselves (Hollands, Pritchard, Stephens, Solly, Wiggins, Hamer, Green etc) or for them to turn their career around after bad moves (Kermorgant, Morrison, Haynes etc). I doubt many of them would care anywhere near as much for the club as they do if CP were to leave.
Unless we were to bring in a massive name (i.e Redknapp, Curbishley) then I can't think of any available manager who would be able to push us up the table in the way Sir Chris can and will.
Even if results don't improved and we end up relegated, I'd rather be relegated with Chris Powell at the helm than with some journeyman who has no association with the club.
By the way Chrissy, who's been calling for his head?
