"Don't get me wrong, Sami is far from finished at Liverpool, but I'm sure we're going to see the partnership of Carra and Agger develop and I think Sami is at a stage of his career where he realises he won't be starting every match.
"I thought Agger was unfortunate not to start against Everton, but you could understand the decision to bring Carra straight back in.
"Now it's up to him. If he plays against Chelsea and performs well again, you can see him being established as a first team regular quicker than we thought at the start of the season."
And Molby added: "There were unrealistic expectations in Denmark when Agger first signed, with some people expecting him to force his way into the team immediately.
"That was never going to happen, but the few months he had here last year have worked to his advantage."
