Borussia Dortmund accuses Bayern Munich of tapping up Reus

An already acrimonious relationship between Bayern Munich and Borussia Dortmund is getting worse. 

Dortmund's CEO is accusing his Bayern counterpart of "unsettling" Marco Reus as rumours continue to swirl regarding the prolific German international's future. 

Bayern Munich chief executive Karl-Heinz Rummenigge made the comments in an interview with German newspaper Bild, stating Reus has a €25 million release clause in his contract, and that the 25-year-old was a "very interesting player," according to the Guardian. 

Rummenigge then called the release clause itself, "dangerous." 

It's easy to see why the folks at Dortmund are aggrieved, especially after the departures of Mario Gotze and most recently, Robert Lewandowski this summer, to Munich. 

Dortmund chief executive Hans-Joachim Watzke released a statement on Wednesday outlining his club's annoyance. 

Borussia Dortmund has noted with some irritation that Karl-Heinz Rummenigge is currently discussing internal BVB matters in a three-day rhythm in the media. We are sure that it is quite clear to anybody interested in football what intentions lie behind such remarks. Karl-Heinz Rummenigge is also fully aware that his behaviour is only going to further damage an already tense relationship between Borussia Dortmund and Bayern Munich.

Naturally as employers, we are going to continue to follow our principles in future and not discuss any details of our employees’ contracts in public.

Reus missed the World Cup due to torn ankle ligaments and is not expected to play in Dortmund's Super Cup fixture versus Bayern Munich next week. He did, however, tell Kicker that he was ahead of schedule in his recover.
