Dortmund's "Borussia" defender Ilkay Gundogan is not yet certain about his future with the German vice-champions.

The 23-year-old footballer, who currently has been struggling with a back injury, is being courted by Madrid's "Real" and "Manchester United".

"I have not yet decided about my future, but for now my first choice is the "Borussia" team," said Gundogan to "Bild Sport".

"I think, soon I will make a decision and come to a final conclusion. At the moment my main goal is to regain good physical shape after the back injury," added the German national team player.

The defender's contract with the Dortmund team is valid until the summer of 2015.
