Borussia Dortmund haven't ruled out signing Mario Gotze this summer with Bild reporting a deal is done.

Gotze joined Bayern from Dortmund three years ago after the Bavarians activated a €37 million release clause in his contract.

Although Gotze has entered the final year of his contract, Bild reports that Bayern have not opened any talks over a new deal. Bayern has made it clear to Gotze his future is not at their club.

Dortmund were reportedly willing to pay €23 million, €4 million below Bayern's own valuation, but later on Friday Bild reported that the two club's had reached an agreement.
