Chelsea are in advanced discussions to sign Pierre-Emerick Aubameyang from Barcelona.
Sky Sports states that a deal worth between £15m and £25m is close to being agreed.
Aubameyang has already agreed personal terms with the Blues after agreeing to the move following talks with Thomas Tuchel.
Tuchel is keen to work again with Aubameyang, who scored 79 goals for him in two seasons at Borussia Dortmund.
