Borussia Dortmund manager Thomas Tuchel says the club holds no grudges against former captain Mats Hummels for his decision to leave the club and join FC Bayern München.
Hummels will likely receive a frosty reception from the crowd at Signal Iduna Park when he returns with the Bavarians for the DFL-Supercup on Sunday.
However, while Tuchel admits it was a bitter pill to swallow, he says the decision was understandable considering he was joining one of the top clubs in the world.
"He has gone to a club that are actually a step up from Dortmund. But it is obviously very bitter that he has strengthened a direct rival by doing so. There is no doubt about that," he said ahead of Sunday's match.
"Mats has made the decision to join one of the best clubs in the world.
"It will be very hard to end Bayern's dominance. They have not lost any key players and have strengthened even further with Mats.
"But we are in no way offended by his decision and are not holding it against him."
The coach also urged the home fans to support Mario Gotze, who moved in the opposite direction after three unsuccessful years with Bayern.
"Mario is a Borussia Dortmund player and should be supported by our fans," Tuchel added. "I expect this to be the case on Sunday against Bayern as well."
