Chelsea have reportedly expressed an interest in signing Borussia Dortmund forward Pierre-Emerick Aubameyang.
The 25-year-old scored 13 times in the Bundesliga last season after completing a move from Saint-Etienne.
According to France Football, the Blues have made contact with the player and are preparing to make an offer.
Aubameyang started his career with AC Milan, but failed to make a first-team appearance at the club.
