Baba Rahman is one of many players with an uncertain future at Chelsea, having been on the periphery for years while being behind three left-backs in the pecking order under Thomas Tuchel.
The 27-year-old doesn’t have a squad number for the new season and has entered the final year of his contract at Stamford Bridge, so Chelsea are desperate to cash in now rather than risk losing him for nothing.
Baba joined Chelsea for £20m from FC Augsburg in 2015 and has gone on to make only 23 appearances in all competitions, the last of which came in 2015/16.
