Or in other words that's quite impossible. Her disciple hit her limit. So I really wonder how Sakura is suppose to self-train herself which won't happen.I see it this way, if you follow the pattern, both Naruto and Sasuke developed more after their sensei's died (yes, Orochimaru is back, but after he died the first time, Sasuke became stronger). Sakura's sensei is still alive, once she dies Sakura will start to gain character development. Hence signalling the next generation taking over from the last.
The only thing left for her is dating.
