The midfielder bought the curtain down on six years as a Red in the summer when he joined Brighton.
Injuries hampered his plans in his final years at Liverpool but he still clocked up 178 appearances for the club.
Tonight he will return to Anfield with the Seagulls looking to cause an upset.
Upon his departure Klopp heaped praise on the 32-year-old, which the player himself thought was unjust, but the German is adamant it is deserved.
“Our visitors today have many talented players but there is one we are very familiar with at LFC,” he told the club’s website.
“I will have to stop myself saying too much on Adam Lallana because I could write a book.
“And I have to be respectful to the fact he is our opponent today… he wants to beat us and we him.
“But I must mention what a special person he was for us – and in truth remains so.
“When he left, I described him as a Liverpool legend for his contribution and I read somewhere recently he felt a little embarrassed by that.
“But he absolutely shouldn’t. It’s a status he has earned and then some.
“Thirty-six Premier League matches a season I look forward to seeing Adam play. There are two when I do not… today is one of those.”
Lallana was signed by Brendan Rodgers in the summer of 2014 from Southampton.
He played in Klopp’s first game as Reds manager at Tottenham in October 2015.
His final goal came late in the day at Old Trafford to secure a 1-1 draw nine games into the season and preserve their unbeaten record, one that would last for 27 games.
