Reds captain Gerrard's Anfield future has been the subject of speculation for several months and he is believed to have decided to continue his career overseas when his contract expires in the close season.
The 34-year-old midfielder, who scored two penalties in Thursday's 2-2 draw against Leicester at Anfield, has already been linked with a move to MLS franchise LA Galaxy and a Daily Express report says he is poised to go public on his plans later Friday to avoid speculation over his future becoming a distraction during the rest of the season.
Former Liverpool teammate Jamie Carragher described Gerrard's decision as a "sad day".
"Sad day for Lfc & English football with the Gerrard news, I think it's the right decision all things considered," tweeted Carragher, who himself made 737 appearances for Liverpool.
