Borkovic, who has played for all teams up to the first team since the U9, has already completed the medical tests in Hoffenheim.
General Manager Peter Stöger: "Alex approached us with his ambition that he would like to move to Germany. Of course we don't want to take away this chance, he has a wonderful task ahead of him there. At the same time, it is a very good signal for us that our players can make it into a top European league with ambition and commitment. We wish him all the best and much success in his future career."
