Binder, 19, has impressed sufficiently in first-team training that Bayern want to secure his long-term future, with a deal running to 2030 expected to be signed shortly, according to Transfermarkt.
Several 2. Bundesliga clubs have made enquiries about the winger in recent weeks, though any interest so far has centred on a loan rather than a permanent switch, and Bayern intend to keep him in Munich at least until the winter break.
Musiala's situation remains more delicate. The 23-year-old is expected to miss Wednesday's Cup tie at VfL Osnabrück, according to Sky, though that is not necessarily a setback: he continues to train fully with the squad, with the club prioritising a careful, risk-free build-up over rushing him back into competitive action.
Musiala disclosed last month that he has been diagnosed with treatable absence seizures linked to a neurological condition, after collapsing during pre-season friendlies against RB Leipzig and Heidenheim. His medication has since been adjusted, and Bayern want to see him handle a full training week without complications before returning him to matchday squads.
The contrast between the two situations - one player being carefully protected, the other quietly rewarded - reflects the breadth of Bayern Munich's squad planning this season, balancing the health of an established international with the long-term development of a teenager still establishing himself.
Neither situation is expected to be rushed, with head coach Vincent Kompany's staff working closely with medical and fitness departments to manage both cases on their own timeline.
For Musiala, the emphasis has shifted from a fixed return date to simply monitoring how his body responds to the adjusted medication over a full week of training.
Bayern's approach has been deliberately unhurried since he went public with the diagnosis, with the club stressing there is no immediate health risk but wanting certainty before exposing him to the intensity of a competitive fixture again. An appearance against Schalke at the weekend remains possible, depending on how the coming days of training go, though nothing has been ruled in or out.
