I'm just delighted that I'm going to be part of it for even longer, says England international Lallana.
Adam Lallana expressed his delight after putting pen to paper on a three-year deal with an option to renew for a further year.
The 28-year-old, who joined the Merseyside club from Southampton back in 2014, signed a new deal with the Reds worth around £110 000-per-week.
Lallana said as Liverpoolfc.com reported: "I'm very proud and feel quite humbled by the show of faith from the club and the manager in particular.
"Signing for a club like Liverpool is obviously a big thing - but to re-sign shows you've obviously contributed enough that the people who make the decisions want you to stay longer.
"This is a really good place to be at the moment and, for a player who wants to be part of something special, I can't think of a better club to commit your future to.
"We have a brilliant squad of players who are only going to get better the longer we are together. We have a world-class manager and coaching staff.
"And because it's Liverpool there is that added X-factor of the supporters and what success would mean to them when we achieve it here. I'm just delighted that I'm going to be part of it for even longer."
