Bayern Munich have fired the father of Borussia Dortmund star Mats Hummels from his role as youth coordinator, according to Bild.
Herman Hummels had been associated with the Bavarian club for a number of years, fostering youth talents such as his son, who swapped the Allianz Arena for Signal Iduna Park in 2009 after a successful loan spell.
His position will be filled by Franz Beckenbauer's son, Stefan, who has been coaching in Bayern's youth ranks since 2001.
BVB currently top the Bundesliga table, five points ahead of Bayern. The two rivals are set to meet twice in the coming months, in the league on April 11, and in the DFB-Pokal final on May 12.
