I think sacking him now would probably bollocks things up even further. If he somehow steers us away from relegation and we survive I'd look to replace him at the start of next season though.
Iwouldn't normally say get rid after only half a season in charge but Houllier is an exception. Carry on and we will be bottom.
We are in freefall, was there really less than 33k there? Was there any anti-Ged chanting?
If they are to grow the gonads to sack him they need to do it now, let us right off the FA Cup match and get prepared and up for the Blues game.
