The only thing left for her to learn from sarada is byakgou
And it depends if Naruto has any noteworthy skills he gained during the time skip the only thing now I can see her learning from him is rasenshuriken
She already got Sakura's CES and I have a feeling the reason we haven't seen her fight much is because she's storing her chakra to awaken Byakogou very soon. Kishi not letting Itachi's niece being fodder
I just hope she has a unique style of fighting something like Itachi and a little less of Sakura

I dont see what naruto can teach but Shadow clones, Sexy Jutsu, and Rasengan.
Naruto can teach Sage Mode or give Sarada the toad summon which teaches Sage Mode.
Sarada with Sage Mode and Byakogou would be powerful.
I guess, Konohamaru taught himself rasengan then?He can't teach it, Naruto isn't a teaching type of ninja. He barely got the mechanic behind the jutsu, he just does it.
And eww, Sarada would never have the toads unless it's under some kind of genjutsu.
Bad Fanfic......naruto won't teach her anything but his death will make her awaken teh sunnigan...
