Top club send message to Arsenal, Liverpool about 28-year-old striker
Borussia Dortmund will listen to offers for striker Pierre-Emerick Aubameyang in the summer transfer window

Borussia Dortmund have confirmed that Pierre-Emerick Aubameyang is available to sign in the summer transfer market.
The Gabon international was thought to have handed in a transfer request last week in an attempt to secure a move away from Westfalenstadion ahead of the start of the 2017-18 season.
Aubameyang has been linked with a potential move to Liverpool this summer considering his past working relationship with Jurgen Klopp and the Reds lack of a proven goal-scorer.
Arsenal have been touted as another potential destination for the Bundesliga’s top goal-scorer as Arsene Wenger looks to overhaul his Gunners squad following a disappointing season.
Chelsea and Manchester United have both been linked with a move to sign a striker in the transfer window, although Romelu Lukaku and Alvaro Morata would appear to be their primary targets.
Dortmund chief executive Hans-Joachim Watzke confirmed that the Bundesliga giants are open to offers for the centre-forward this summer.
“We will listen to it when a club is willing to show its appreciation for Aubameyang in a financial way as well,” Watzke told Bild, as quoted by Metro.
Aubameyang scored an impressive 31 goals in 32 appearances in the Bundesliga last season to beat Bayern Munich rival Robert Lewandowski to the league’s golden boot.
