The 28-year-old moved to Anfield from Chelsea in 2013 and has scored 48 Premier League goals from 98 outings, but it is a number of years since he has been a real force.
In combination with Luis Suarez, the England forward bagged 21 goals from 29 top-flight appearances in the 2013-14 season and has been capped 26 times by the Three Lions.
However, a combination of injuries and a dip in form has seen Sturridge’s star wane in recent times and he is now down the pecking order at the Merseysiders after scoring twice from nine games this term.
Rumours persist that he may be sold or go out on loan in the new year, with Betis said to be keen.
Quique Setien's side have been strongly linked with a move for Arsenal midfielder Jack Wilshere and may double up on their English targets if rumours surrounding Sturridge are true.
