Sabitzer looks set to end his stay at the German champions this summer, and he has opened the door for a switch to Bundesliga rivals Borussia Dortmund.

A deal looks extremely close, according to Florian Plettenberg, who revealed on Monday morning that the midfielder will join up with his teammates on their U.S. tour later this week.

Sabitzer has reportedly signed a four-year deal at Dortmund, with the German club paying a total of $28 million, including add-ons.

The Austrian could make his debut for his new club against Manchester United in Las Vegas on July 31.
