Jonas Urbig, the 23-year-old seen as the heir apparent both at Bayern and potentially for the national team, is the man widely expected to succeed him whenever that moment comes.
Nobody at the club is in any doubt that Urbig should eventually rise to become Bayern's new number one. What is less clear is how the rest of the goalkeeping department will be reshaped, given that Neuer's long-serving deputy Sven Ulreich, 38, is also expected to retire at the end of the season if things go as anticipated.
According to Kicker, at least one and possibly two new goalkeepers could join Bayern next summer as a result.
The priority is an experienced number two to sit behind Urbig. Daniel Heuer Fernandes, 33, was linked with that role earlier in the year, but after Neuer extended his own Bayern contract by a further year, Heuer Fernandes instead prolonged his own deal at Hamburger SV through to 2028. Oliver Baumann, 36, of TSG Hoffenheim, was also the subject of speculation at the time.
For a potential third-choice goalkeeper, sporting director Max Eberl and his staff could turn to an academy product for next season. Germany youth international Leonard Prescott is regarded as a genuine talent, though at 16 he remains very young for such a role.
Jannis Bärtl, 20, and Leon Klanac, 19, are seen by Kicker as having fewer prospects of a path into the first-team picture in the near future.
Whatever shape the department ultimately takes, Bayern's leadership appears committed to ensuring Urbig's transition into the number one role is properly supported, rather than leaving the 23-year-old to fill Neuer's boots without adequate cover behind him.
Urbig joined Bayern Munich from 1. FC Köln, where he had established himself as one of the most promising young goalkeepers in German football, and has continued to develop steadily behind Neuer since his move to Munich. He has already earned recognition as a future national team option too, having received his first senior Germany call-up earlier this year before injury ruled him out.
Neuer, now 40, remains Bayern's undisputed first choice for as long as he continues playing, but the succession planning taking shape behind him reflects the scale of the challenge facing whoever eventually steps into his gloves on a permanent basis.
