World Cup postmortem

How could the same starting eleven players who played so well against Italy (albeit they lost) play so dismally against Uruguay?  I know very little about the technicalities of football and I have no answer, but against Italy we looked (for the first time in ages) like a team, like we knew what we were doing, like we had a plan, and like we were capable of scoring goals.  Yet against Uruguay we were back to looking clueless, disjointed, and lacking any sort of penetration.  And it doesn't take a footballing genius to point out that three (and you could argue all four) of the goals scored against us were the result of basic defensive errors, so perhaps that's where we should be concentrating our efforts to improve.  Anyway, that's it for another couple of years. Hope springs eternal!
