Borussia Dortmund general manager Hans-Joachim Watzke has revealed they will not be having lunch with Bayern chiefs when the two teams meet this weekend as relations between the sides have deteriorated.
Dortmund welcome the Bundesliga champions to Signal Iduna Park on Saturday in what will be a dress rehearsal of the Champions League final on May 25.
And Watzke, who recently saw prized asset Mario Gotze confirm his move to the Allianz Arena, says there has been incidents recently which have irritated him.
"I have always spoken about Bayern with great respect and admiration. But I must say now that things have cooled off a little. There have been a couple of irritations recently," he told Bild.
"Everything should go off in a fair, sporting manner on Saturday but there will not be hugs all around like before.
"Why should we act as if everything is hunky-dory? "There won't be any lunch with Bayern, just a handshake."
