Kenny Dalglish claims Steven Gerrard's rehabilitation is "progressing brilliantly" but has refused to set a date for his possible return.
The Liverpool skipper has endured an injury-hit 2011/12 campaign, with an ankle infection currently keeping him on the sidelines.
The Reds are reluctant to gamble on his fitness, with one setback having already been suffered this term.
It remains unclear when Liverpool supporters can expect to see their captain back in action, but Dalglish is confident Gerrard will be back sooner rather than later.
"Steven is progressing brilliantly," he told the club's official website.
"There is nothing that's been a disappointment other than he's not been available for selection.
"He'll be available as and when he's over what he's got but everything's going really well. We couldn't ask for more or any greater news from him."
Pressed on whether a timescale could be put on his recovery, Dalglish added: "No. When he's ready."
While the Reds are still waiting on Gerrard, they are set to welcome Jamie Carragher back into the fold for Sunday's trip to Chelsea.
"Carra is training," said Dalglish.
"He's got rid of his calf injury so he's fit and available for selection."
In-form forward Luis Suarez will also be in contention for a starting berth against the Blues having reported back from international duty with Uruguay free of a slight back complaint.
"So far we've had no news of anybody being injured," said Dalglish.
