Borussia Dortmund would reportedly be prepared to sell Pierre-Emerick Aubameyang if they can fetch more than £40m for his services.
The 26-year-old joined Dortmund from Saint-Etienne in 2013 and has netted 63 times in 114 appearances for his German club.
This season, the forward has already notched 22 times in just 20 appearances, which has led to talk of interest from the likes of Barcelona.
According to Bild, Dortmund have set the Gabon international's price at £42m and will refuse to sell unless that figure is met.
Aubameyang is still on the same five-year contract that he signed upon joining Dortmund in July 2013.
