In the manga we see Sarada with 3 tomoe Sharingan using Fire ball, Phoenix Flower, & Chidori. If Sasuke is shown training her in these areas in the anime, or is atleast mentioned to have done so with the training being offscreen. Will you acknowledged manga Sasuke? Afterall, at that point they're making it blatantly obvious that he trained her.Get that thread going and tag @Naruto X Hunter so he can read over it, asap.
Aside from the bet, sure, I'll say fillersuke trained Sarada (if he actually trains her). As for being sure, no I wasn't since we have filler novels saying he trained her. There's always a possibility that he could train her in filler. The bet was moreso on a different aspect of training.
@bold No need to say it like that since episode 168 preview literally shows them training.
