Jupp Heynckes' successor at Bayern Munich will be unveiled at the end of April, with CEO Karl-Heinz Rummenigge ruling out the possibility of former Borussia Dortmund manager Thomas Tuchel taking charge of the Bundesliga leader.

Bayern turned to Heynckes earlier this season following the dismissal of Italian manager Carlo Ancelotti. The 72-year-old, who came out of retirement to help the club he spent three previous spells with, has since taken the team on a dominant domestic run toward winning its sixth consecutive league title, as well as a berth in the Champions League quarter-finals.

After months of speculation over Heynckes' role with the club beyond this season, Rummenigge confirmed that a new manager will be announced in the coming weeks.

"I'm working on the basis that we'll present our new coach by the end of April at the latest," Rummenigge told Sky Sports, as translated by Bundesliga.com. "But there's no rush, we're quite relaxed. We've already hired coaches just a few days before the start of training. The credo is: We want a German-speaking coach. And that's how it'll be."

Rummenigge added that Tuchel won't be in the running, because the 44-year-old informed Bayern that he's accepted a role elsewhere.

"Our sporting director Hasan Salihamidzic has held talks with coaches and Tuchel was among them," the CEO said, noting that he couldn't say a "bad word" about Tuchel.

"He informed us that he's signed for another club. But that isn't a problem for us, we are relaxed."

Eintracht Frankfurt's Niko Kovac has emerged as a leading contender for the Bayern job.

Tuchel, meanwhile, is expected to succeed Unai Emery at Paris Saint-Germain. The club has reportedly offered him a two-year contract, though he hasn't signed yet, a source told Jonathan Johnson of ESPN FC.
