While Nagelsmann already has a backup plan in Baumann, he still has faith in Ter Stegen, suggesting he will be between the sticks at the World Cup.
Speaking to ZDF, he said of Baumann: "Because I think he played very well for us and has also been playing very consistently in the Bundesliga over the past few years. Baumann is a good footballer who helps us in the build-up play [and is] a reliable character who is good for us and deserves his chance."
When asked about whether he'll be selecting Neuer or Ter Stegen, Nagelsmann said: "I have my plan in mind, and that is for Marc-Andre ter Stegen to play again when he's healthy. We're keeping our fingers crossed that his rehab goes well, and it currently looks like he'll be healthy again by winter, and then we'll see how things go for him.
"Of course [Ter Stegen] has to play, he knows that, it's part of the job."
Asked about Neuer's possible return, he added: "I'm still keeping my fingers crossed that Manu has a good season. The Club World Cup was very, very good, as was the start of the Bundesliga season. So I'm optimistic that he'll have a good season as well. But with us, I have my plans well in mind."
