Borussia Dortmund chief executive Hans-Joachim Watzke has insisted that the club's star players Pierre-Emerick Aubameyang and Ilkay Gundogan will not be sold this month.

Aubameyang has been linked to Arsenal and Liverpool, while Gundogan is believed to have attracted interest from Premier League clubs and Juventus.

However, the Dortmund CEO has claimed that the club will not be budged.

"I can rule out the transfer of any of our top performers now," Watzke told reporters. "That's definitely not on our agenda."

Last week, Aubameyang was named 2015 African Footballer of the Year, beating Manchester City midfielder Yaya Toure.
