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.
The 33-year-old moved to Barcelona on a free transfer from Arsenal in January.
Tuchel is keen to work again with Aubameyang, who scored 79 goals for him in two seasons at Borussia Dortmund.
