The debate over Germany's goalkeeping hierarchy has dominated the build-up to the tournament after Neuer was reinstated as first-choice goalkeeper just weeks before the World Cup, displacing Oliver Baumann.

While Muller supports the decision from a sporting perspective, he suggested the communication surrounding the move could have been handled better.

"The discussion naturally got heated because the communication was questionable," Muller told ran. "But in terms of the game itself, I can understand it."

The former Bayern Munich forward stressed that Baumann should not view the situation as a demotion.

"That's not a demotion for Baumann. He just has to be ready and help us when we need him."

Neuer, who recently recovered from a calf injury, remains Germany's premier goalkeeper in Muller's eyes.

"What really sets Manu apart is his positioning and footwork," Muller said. "When he's feeling physically strong, he's simply the best in goal."

However, Muller also praised Baumann's ability and mentality after the veteran goalkeeper impressed during Germany's recent win over the United States.

"We don't need to worry at all because we've seen it: Oli Baumann is so good - not just in terms of his goalkeeping skills, but also mentally - that if Manu can't play, he's there."

Baumann admitted he initially struggled with Nagelsmann's decision to bring Neuer out of retirement and restore him as Germany's number one.

"It was tough at first; I didn't feel entirely cool about it," Baumann said. "But it was clear from the start that I'm here for the team."

Despite the controversy, Muller believes Germany head into the World Cup in a strong position after winning nine matches in a row.

"We've built up a certain amount of confidence - nine wins in a row don't go unnoticed," he said.

The 2014 World Cup winner also reflected on Germany's disappointing campaigns in 2018 and 2022, suggesting fine margins played a major role in both early exits.

"If Jamal Musiala's shot against Japan in 2022 had gone in instead of hitting the post and crossbar, we'd have advanced and wouldn't have had a disastrous group stage," Muller said.

"You also need that little bit of luck."

As Germany prepare for another World Cup challenge, Muller believes the squad has the unity and quality required to compete for the trophy.

"You don't need perfect conditions," he said. "What you do need is for the team to feel like we're on the same page. And I do feel that we're heading in the right direction."
