Williams aside, them having a few players out by no means turns this into an easy game. Their replacements will be keen to impress.
Besides, when have you ever known a Mick McCarthy side roll over?
Is the Selhurst Special One fit for once? I've not seen him mentioned in many Ipswich reports lately, so am assuming that either he's injured (natch), or I missed that transfer to Real Madrid/ Barcelona (I forget which) during the last transfer window.
