(CNN) -- UEFA have opened an inquiry after German Bundesliga champions Bayern Munich started legal proceedings over one of their employees.
Bayern confirmed on Wednesday that they were taking Peter Limacher -- the head of UEFA's disciplinary committee -- to court for slandering the club's name in an interview with German weekly magazine Stern.
According to the article, Limacher claims his colleague, Robin Boksic, had informed him that Bayern had been bribed to lose their 2008 UEFA Cup semifinal to Russian side and eventual winners Zenit St Petersburg.
However, Limacher has subsequently denied making any such comments to the magazine and European football's governing body have now decided to investigate the whole situation.
A UEFA statement read: "Michel Platini, president of UEFA, Gianni Infantino, general secretary of UEFA, Karl-Heinz Rummenigge, chairman of Bayern Munich and Karl Hopfner, vice-chairman of Bayern Munich discussed recent events that have been covered in the news media and agreed on the need to have absolute clarity on the matter.
"In an open and constructive conversation, it was mentioned that, in the light of the recent press coverage, UEFA understands the reasons for the reaction of Bayern Munich .
"Bayern Munich has been informed that, in order to clarify the case, UEFA has already opened an internal investigation into the whole matter," continued the statement.
Following Bayern's 2-0 Champions League victory over Roma on Wednesday, Rummenigge released a club statement confirming their intention to start legal proceedings over the matter.
The Bayern statement said: "These comments are totally untrue and slanderous. We are completely white as snow in this case and Bayern will not allow our reputation to be tarnished. These two employees of UEFA cannot keep their positions."
However, in an interview with the German media on Thursday, Limacher denied he had made any such comments about the club.
"It is unfounded, I never said that," Limacher told the Financial Times Deutschland. "I am not aware of any payment at Bayern Munich where sums of money were found amounting to seven-figures in order to manipulate a game."
