Bayern Munich's director of sport Matthias Sammer has hit back at suggestions his relationship with coach Jupp Heynckes is strained.
Sammer took over as Bayern's director of sport in July, having been technical director of the German Football Federation (DFB) since 2006, but the move has attracted some criticism here.
Eintracht Frankfurt's chairman Heribert Bruchhagen said Sammer's presence on Bayern's bench can only serve to unnerve Heynckes.
And ex-Germany and Bayern captain Oliver Kahn, who now works as a television pundit, has said Sammer was acting like a second coach in Munich.
But Sammer hit back last weekend by telling German Sky any suggestion of his strained relationship with Heynckes is "total crap" and expanded on his reaction to German daily Bild.
"I have asked Heribert Bruchhagen directly if he has a problem and he hasn't, but with Oliver Kahn it is a different matter," Sammer told Bild.
"We have a good relationship, but I have already told him a thousand times how I see the role of the sports director and the coach.
"We have often talked about this and exchanged ideas.
"Now he superficially criticises my role here, even though he knows the context.
"He knows I am not a second coach, that has disappointed me greatly.
"Oliver Khan has a strong influence on football in Germany and he must be aware of the effect his words have.
"What he says will be heard and believed by our head coach and our fans."
With Heynckes' contract set to expire in June, Sammer insists the decision of when 67-year-old will quit his position will come from the coach alone.
After several reports appeared in the German media last season that ex-Barcelona coach Pep Guardiola is being courted to replace Heynckes, Sammer rubbished the claims.
"We haven't talked about him and we haven't discussed a single candidate," insisted Sammer.
Bayern are top of the German league table after two games having hammered VfB Stuttgart 6-1 last Sunday.
