Did we really do much of that though? I recall that for most of these games we were playing a near-full first team squad with maybe 2,3 or 4 changes - it's not exactly in the same league as Wenger's League Cup teams.
Southampton away 3-0 was awful. What about those FA Cup/Carling cup replays - Wrexham, Woking (was that Gus?). West Ham 6-0, Reading 3-0.
Edit - Watford away second time round was every bit as bad as it gets. That was truly awful.
