Blackpool midfielder Charlie Adam is on the verge of completing his move to Liverpool after passing a medical at the club's Melwood training complex on Thursday.
The Reds agreed a transfer fee, reported to be around £7 million, with Blackpool on Wednesday and Scotland international Adam is expected to agree personal terms within the next 24 hours.
Kenny Dalglish has made it clear ever since he returned to the Anfield hot seat that he wanted Adam, but an initial attempt to sign him in January collapsed.
The Scotland international will now become Dalglish's second signing of the summer as the Reds boss has already bought England international Jordan Henderson from Sunderland for £16 million.
Aquilani has returned from a season-long loan spell at Juventus, who chose not to take up the option to buy the Italy international, while Poulsen became a peripheral figure when Dalglish took over in January.
There are a number of other players Liverpool would like to move on in order to free up space not only in the squad but on the wage bill. Joe Cole and Milan Jovanovic are two players who failed to impress in their first seasons with the club.
Meanwhile, Liverpool defender Glen Johnson is looking forward to the new season with confidence having signed a contract extension at Anfield.
The England defender, like many of his team-mates, endured mixed fortunes in the previous campaign as he looked woefully short of form under Roy Hodgson but was rejuvenated after Dalglish's arrival in January, playing well out of position at left-back.
Johnson has committed his long-term future to the club and admitted it was an easy decision.
"I'm very pleased. I've been here a couple of years and it's great to be staying here for a few years longer now,'' he said. "For the club to want me to be here is a great feeling and I did not have to think twice about signing.
"I think I am improving all the time at Liverpool. You're never too good to improve - and my aim is to just keep improving.
"With the squad we've got now, the backroom staff and the way things are going, things are looking positive. The club is looking to bring a few more players in, so the future is looking bright.
"We've made a couple of good signings already and with a few more we will be a right force in the coming season. I'm quietly confident (about the new season). If we take it game-by-game I think we'll do well.''
