Bayern Munich vice president Karl Hopfner has insisted that he will not be apologising to Dortmund’s chief executive Hans-Joachim Watzke.
The rift between the pair stems from a disagreement in the details of a loan that Bayern paid Dortmund in 2004, a figure reported to be €2 million.
Watzke had initially claimed that Dortmund would have to pay eight per cent interest on the loan, before retracting the statement following fierce denials from Hopfner, who protested the rate of repayment was much lower.
"I have not insulted him, but placed only the facts on the table,” Hopfner said to Kicker.
When questioned whether there would be any apologies, Hopfner replied: “Certainly not, absolutely not."
Despite admitting his initial error, Watzke went on to refute claims that Bayern’s loan saved Dortmund and aided their recovery from past financial problems.
Speaking to Welt am Sonntag, Watzke said: “Bayern have given a loan to my predecessor in the previous year, and in February 2005, BVB was insolvent. So there you go: where have Bayern Munich contributed something to the rescue?"
Hopfner, who is currently interim president, will officially replace Uli Hoeness on May 2, after he was given a jail sentence in March for tax evasion.
