"We hope we're getting back to the form of last season, but there's nothing worse than talking about it and not doing it," said the Reds' vice-captain.
"We can judge that at the end of the season, but what we did last season will be difficult to achieve again. If we can get close to 25 clean sheets for the season, then that will be good. It is similar to strikers, they want a goal every other game and we should be looking for a clean sheet every two games.
"We are not going to get carried way. Everyone knows we have not had the greatest of starts in the Premiership, but we have been doing very well at home and we have another home game on Wednesday. The teams around us are quite close, so if we can get a good result on Wednesday and some of the teams around us drop points then that can put us closer to the top four.
"We did have difficult fixtures at the start of the season, but we are Liverpool and we should be a difficult fixture for the opposition.
"We are not hiding the fact that we are disappointed with those results but we have got to look forward now and the only positive is that a lot of those tough games are now out of the way."
