Borussia Dortmund won the Bundesliga in 2011 and 2012, but have had to watch Bayern Munich run away with the league in the past two seasons while also acquiring Mario Götze and Robert Lewandowski. 

“We absolutely do not see the need to sell players who have an existing contract,” CEO Aki Watzke told Sport Bild.

Ilkay Gundogan has been one of the Dortmund players linked with a move away from the club this season.
