Lallana will leave Liverpool as a Premier League winner after Sunday’s final game of the season against Newcastle United at Saint James’ Park.
Lallana, whose contract was due to expire last month, signed a short-term extension to complete the 2019/2020 season with Liverpool but has not featured in any of their games since the restart as Jurgen Klopp guides against any potential injury that will jeopardise his next move.
Lallana has played 15 times in the top flight this season, with his only goal coming in the 1-1 draw at Manchester United back in October.
The 32-year-old joined the Reds from Southampton in the summer of 2014 and has won the Premier League, UEFA Champions League, UEFA Super Cup and FIFA Club World Cup during his time at Liverpool.
On Friday evening he posted a picture of himself with his Premier League winners' medal to his Instagram account, along with a message which read: "Nothing but love and appreciation for the last 6 years.
"Thanks to the amazing people who made this place feel like home. To the supporters for accepting me and making me feel like one of their own.
"The staff - the world-class staff - without whom none of what we achieve as players would be possible. I can’t find the words to do justice for how much they mean to me... they are everything!
"To Brendan Rodgers, I will forever be grateful that he gave me the privilege to represent this club. To Jürgen Klopp, an even better man than he is a football manager.
"My teammates, they are my brothers. To share this journey with these boys has made me feel the luckiest fella in the game. To the Skip, Jordan Henderson... my best friend! No one deserves success more than this guy. It’s meant everything to be at his side while he’s achieved it.
"And to my own family, my wife and children, my mum, dad and sister... my own “team”. They made the good times better and the tough times bearable.
"I am so grateful to have been part of this special place. And now on to the next adventure.
"With love, Adam."
