After 15 matches of the season Brendan Rodgers' side are 11th on 19 points, 17 behind leaders Manchester United and seven adrift of Champions League qualification having won only four games and drawn seven.
A year ago, under Kenny Dalglish, the team were sixth, 12 points off the top and just three behind fourth place with seven victories and five draws.
There is more of a similarity between the two regimes in relation to their failure to convert chances despite dominating games but Agger thinks they are better now than then.
"The last couple of games we've played really well," said the Denmark captain. "I think the Tottenham game (a 2-1 defeat last Wednesday) was one of the best games I've played in for a long time - we played them off the pitch.
"Confidence is a big thing here and I think we have it. We are brave on the ball, want to go forward and we are not just playing around and I think that is the difference. I think we are creating more chances than last season. I don't see the statistics but the feeling on the pitch is we are creating bigger chances.
"It is difficult to compare two seasons but it is feeling better now."
Previously seen as injury-prone the 27-year-old is currently enjoying his longest run of Premier League matches in nearly seven years at Anfield, having made a 13th consecutive appearance against Southampton at the weekend.
He would undoubtedly have started every league match had he not been sent off in the season- opener at West Brom and has played 1,210 minutes so far having only been a substitute twice. Agger puts his success down to a change in the way he looks after himself both before and after matches.
"I am doing some different things than I did a few years ago. I am trying to look after myself better. It is just things like the way you train, work in the gym, how you recover -- and I think that is the most important thing."
