Bayern Munich CEO Karl-Heinz Rummenigge has mocked Didi Hamann over his recent claim that Pep Guardiola was in talks to join Manchester City.
Former City midfielder Hamann, who came through the youth ranks at Bayern and made over 100 appearances for the German club, had backed a report from Qatari-owned global sports channel beIN Sports last month that said Guardiola was likely to take over at the Etihad Stadium this summer.
Guardiola, who has one year remaining on his contract, strongly rejected the rumours shortly afterwards, and Rummenigge has now told Sport Bild: "I have to say one thing: Didi Hamman is the second-best narrator of fairytales there is, right behind the Brothers Grimm."
Hamann had said in his role as a Sky pundit that he believed the discussions were advanced but nothing had been signed.
Even so, Rummenigge said he did not bother to find out whether there was any truth to the story.
"Why should I? I fully trust Pep Guardiola, and that's enough," the 59-year-old said.
Guardiola has yet to commit his future to Bayern beyond the end of next season, but Rummenigge said he was "relaxed" about contract talks.
"We will discuss it without distress or excitement," Rummenigge said, reiterating that they will sit down with the coach to discuss the matter later this year.
Guardiola's position came under scrutiny towards the end of the season amid some disappointing performances in the Champions League.
A 3-1 defeat to Porto in April led to the exit of the club's long-serving team doctor Hans-Wilhelm Muller-Wohlfahrt, who said he felt his medical staff had been scapegoated for the result.
The matter led to questions as to whether Guardiola was exercising too much influence at the club, particularly given the uncertainty over the former Barcelona coach's long-term future, but Rummenigge said the Catalan is "not as complicated as it is sometimes reported."
Rummenigge added that Bayern will continue their overhaul of the medical department after a season in which key players such as Philipp Lahm, David Alaba, Javi Martinez, Thiago Alcantara, Bastian Schweinsteiger, Arjen Robben and Franck Ribery spent significant spells on the sidelines.
"We have analysed the injuries after the season, and the result was not too positive for FC Bayern," he said. "We are in the bottom third, both domestically and internationally, when it comes to the injury rankings. That's why we'll invest in the medical and diagnostics department.
"We want to anticipate injuries. A drop of blood will be taken from the pros before training and immediately analysed. We can then see whether everything's fine or not."
Earlier this week, kicker had reported that Bayern will not only take blood samples but also urine samples from their players, which is common practice at clubs like Real Madrid, Barcelona, Chelsea or Inter Milan.
