Mainz manager Thomas Tuchel has rejected reports that he has been approached by Bayer Leverkusen with regard to becoming the successor to Jupp Heynckes.
Leverkusen boss Heynckes' contract expires in June 2011 and there has yet to be a decision about his future.
Tuchel has therefore been rumoured to be in contention to take over at BayArena next summer after his excellent start to the current campaign.
Mainz have a 100 per cent record after five matches to make themselves surprise leaders of the Bundesliga.
But Tuchel insists he has not been approached by other clubs, as he told Sportinformationsdienst: "I have not spoken a single word to anyone from Leverkusen.
"I was feeling fine when I prolonged my contract with Mainz until June 2013."
Bayer Leverkusen general manager Rudi Voller told BILD: "There's not a jot of truth in the reports."
