Hummels blasts Bayern's "calculated" attacks on Dortmund

The Germany international has blasted his former club's CEO for trying to destabilise BVB by publicly revealing the alleged figure of Marco Reus' buy-out clause

Mats Hummels has accused Bayern Munich of repeatedly making "calculated" attempts to "weaken or unsettle" Borussia Dortmund.

The defender came through the youth team ranks in Bavaria before leaving for BVB in 2009, after a year on loan at Signal Iduna Park.

However, despite his close ties with Bayern, he is appalled by what he feels are deliberate and underhanded attempts to destabilise Dortmund, citing Karl-Heinz Rummenigge's recent comments on Marco Reus' buy-out clause as a case in point.

"Bayern have had difficulties for us for years, which is why they try to weaken or unsettle us," the Germany international told Transfermarkt.

"Look at the way Karl-Heinz Rummenigge recently betrayed the alleged contract details of Marco Reus - such statements are calculated.

"But the fact that Bayern deals with us is actually the greatest praise."

Hummels also feels that Dortmund, who won successive Bundesliga titles in 2011 and 2012, believes that Jurgen Klopp's side have upset Bayern with their on-field excellence and argues that they would have claimed even more trophies at their rivals' expense had it not been for poor officiating.

"What if we had had the luck of the referee on our side in the Champions League final [in 2013 when Dante controversially avoided a red card] and the DFB Pokal final [last season when Dortmund had a fair goal not given] - and not Bayern?"

"I think they know that these two victories were lucky and that they could have been very different."

Hummels admitted that he could easily still be at Bayern today had fate not intervened - but insisted that leaving the Allianz Arena was the key moment in his career to date.

"If Bayern had not bought Breno in 2007 for €12 million, I would not have left," he argued.

"But that's the way football is sometimes: I was practically forced towards happiness. It was the best thing that could have happened to me."

Consequently, while Hummels has been linked with the likes of Manchester United and Barcelona in recent times, he has no intention of leaving Dortmund, which is precisely why he insisted against having a buy-out clause in his contract.

"I wanted to set an example with the extension I signed and it will run for five years until 2017."
