Germany national team manager Julian Nagelsmann has praised Gnabry's form, saying he is "hopeful and confident" the winger can maintain a consistency that was disrupted in previous seasons by injuries.
Bayern's winning run has also been fuelled by Michael Olise, who has already scored four goals in the first four matches. The French international only missed the scoresheet in the Franz Beckenbauer Supercup win over Stuttgart, where he played just 45 minutes.
He is on track to match his 20-goal, 23-assist haul from 55 appearances last season.
Gnabry highlighted Olise's qualities in a recent interview with Bild, saying: "He has enormous potential and is one of the best players in the world right now. I don't know where his limit is. Michael can achieve everything. He can play centrally, keep the ball, and is a good 1v1 player.
"I didn't know him that well before he joined and didn't expect things to work like this."
The winger's humble and focused nature has also impressed Gnabry. "Maybe it doesn't seem that way sometimes, given the way he presents himself, but he has a very good mindset.
"Michael works hard, he's a very good guy, very determined. That's why I think he still has a lot of potential," he added.
With Nicolas Jackson joining on loan from Chelsea, Bayern manager Vincent Kompany will be hoping for consistent performances from both Gnabry and Olise.
Jamal Musiala is not expected to return until November, meaning the duo could play a pivotal role in Bayern's push across all competitions in the coming months.
