A sixth home draw against the Premier League’s bottom side Blackburn on Stephen’s Day means the Reds have dropped 12 points from a possible 27 at Anfield.
They have also scored only 21 goals in 18 league matches and Monday’s match followed an all-too-familiar pattern as Kenny Dalglish’s side dominated and created a number of chances but failed to take advantage.
“It would be a problem if we were not creating chances but when we are creating then you can’t complain,” said Agger.
“But when you don’t take your chances, you don’t win football games.
“If you look at all the games we’ve had plenty of chances and possession but it is just that final touch — it is not just one or two players, it is all of us missing chances.
“The only way to solve it is to create more because at some point it has to come.
“I really think for 80% or 90% of the time we are playing well.
“That’s the strange thing, as normally when you play well you get a bit more luck but somehow we are missing that final touch — we need to find that.
“Normally when you try harder you get the luck and that’s what we must keep doing.”
In a lacklustre first half Andy Carroll had a goal disallowed for offside and Maxi Rodriguez was denied a penalty after being brought down by goalkeeper Mark Bunn as the assistant referee had raised his flag when it was Luis Suarez and not he who had crept ahead of the defence.
On the stroke of half-time Blackburn fortuitously took the lead when Charlie Adam diverted Morten Gamst Pedersen’s corner into his own net, and although Rodriguez scored his 11th goal in 12 starts soon after the interval Liverpool could not find the equaliser.
Captain Steven Gerrard returned from a two-month injury absence as a second-half substitute as Liverpool pressed for the winner, but in the last few seconds Carroll was denied by a brilliant save from Bunn and Agger had a header cleared off the line by 17-year-old Adam Henley.
“We had a lot of shots on goal but you have to give credit to their keeper who made a few good saves,” added the Denmark defender.
“Looking at the game we still created chances so the confidence must still be there.
“It wasn’t down to complacency because you know all games in the Premier League are difficult — it doesn’t matter whether you are home or away.
“But when you play for Liverpool and play at Anfield you have to win the games — especially these ones.”
