Jonjo Shelvey was one of the few positives for Liverpool in their Carling Cup defeat to Northampton.
Shelvey's appearance as a substitute in extra-time helped lift Liverpool, with the midfielder playing a part in Ngog's equaliser.
Hodgson told liverpoolfc.tv: "He did well but the fact is he came on in extra-time and people were tiring. We think Jonjo Shelvey is a player with a bright future, but I have to say I am not in the mood for talking about positives.
"We wanted to do well in the Carling Cup and we haven't. We were given a fairly kind draw if you look at the other teams we could have drawn. If you get a team from three leagues below you, you're expect to win and when you don't win, then you can expect to be criticised from the top downwards.
"We must all take responsibility and I am bitterly disappointed that the team I had so much faith in did not repay that faith this evening, with the exception of one or two."
