The German FA has asked Bayern Munich coach Carlo Ancelotti to explain his behaviour after raising his middle finger to Hertha Berlin fans at the weekend.
Exchange with Hertha crowd after draw
The incident occurred as the ex-Real Madrid boss headed down the tunnel after Bayern had earned a late 1-1 draw at the Olympiastadion.
"Ancelotti has been asked to submit a statement on the events that transpired after FC Bayern's match at Hertha Berlin on Saturday," Bayern said on Monday.
"The FC Bayern head coach will of course comply with this request."
Ancelotti: "I made that gesture after I was spat on"
Ancelotti said on Sunday that he had suffered a rush of blood to the head in the face of provocation from the home supporters in Berlin.
"Yes, I made that gesture after I was spat on," Ancelotti told German TV, shortly after his side had scored a 96th-minute equaliser through Robert Lewandowski.
