There were 42 appearances and six goals – two more versus Everton – in a 2019-20 campaign that brought glory in the Premier League, FIFA Club World Cup and UEFA Super Cup.
A reliable and willing squad member, Origi remained on Merseyside until 2022 and added medals for the League Cup and FA Cup before saying goodbye.
His totals showed 175 games and 41 goals wearing the Liver bird.
Having departed on a free transfer that summer, Origi moved to AC Milan, with whom he parted company last December.
His time with I Rossoneri also saw him spend the 2023-24 season back in England via a loan at Nottingham Forest.
Origi represented Belgium at senior international level on 32 occasions and scored three goals.
He continued: “To my fans across the world who helped me shine: every iconic moment, every goal, every piece of history we made together will forever be ours.
“To every club, and all the coaches and teammates who stood beside me, thank you. You shaped me in ways that go far beyond the pitch.
“Representing Belgium, my nation, while carrying Kenya, my roots, was a joy.
“And to my family and those closest to me… without you, I am not who I am today. I am forever grateful.
“The mission is complete. Now I step into my next calling.”
