German club Borussia Dortmund is currently working on a bid to bring Mario Gotze back from Bayern Munich.

The player who joined Bayern Munich in 2013 has failed to make an impact at his current club and might be favorable to a return to Dortmund.
Borussia Dortmund will be leaving for China for their pre-season preparation but are still active on the transfer market. The manager is keen to strengthen the team so as to be able to compete in the Bundesliga.
Dortmund CEO Hans-Joachim Watzke has admitted that there are talks in progress between the two clubs, but they have yet to finalize a deal. The player currently has one year contract remaining with Bayern Munich, but he may be available for the right fee.
Hans-Joachim Watzke said that no agreement has been achieved so far and that they still have to talk with Bayern Munich’s representative as well as the player himself. He stated that it would be a great thing for Mario Gotze to return to Borussia Dortmund but at the moment there is nothing concrete.
