I am a firm believer in stability; we've changed our manager far too often recently, which is partly the reason why we're in the smelly stuff now, so I don't think it's time to sack Sami.
If we were to go down the sacking route, though, I wouldn't risk Calde (great man though he is!) and Jones - I'd go straight for Pulis.
Hell no, not Pulis.
Boring git, no attacking flair whatsoever.
