The midfielder says there are exciting times ahead at the club after their summer business.
Striker Christian Benteke joined the Reds in a big-money move from Aston Villa earlier this week, the latest to arrive on Merseyside this summer.
He joins a growing list of summer recruits, with James Milner, Roberto Firmino, Nathaniel Clyne, Adam Bogdan and Joe Gomez all also having been recruited during a busy transfer window.
And Lallana is enthused by Liverpool's recruitment so far, with Firmino and Benteke yet to feature in pre-season.
"These are really exciting times,” he told lfctour.com.
"Benteke’s a big presence and he’s going to be a massive signing for us. Clyney [Nathaniel Clyne] has settled in brilliantly as have all the others and James Milner has been tremendous. They will be great additions to the squad.”
A great asset
The Reds have so far impressed during pre-season, with a 1-1 draw against a Malaysia XI their only disappointing result to date.
And one player who has particularly shone is youngster Jordon Ibe, who has continued the fine form he enjoyed at the end of last season as he broke into the side.
Many are predicting that he could be the perfect replacement for Raheem Sterling - who left to join Manchester City - with some even suggesting that he will be a better player than their departed star.
Lallana, meanwhile, says Ibe will be a great asset for them in their upcoming Premier League campaign.
"Jordon has been very impressive," Lallana added. "He’s got a great attitude and wants to work hard. He will be a great asset for us this season."
