I'm not sure if this is really the worst, but i think it's pretty bad that Sakura never obviously surpassed Tsunade.

Jiraiya had three aspects that Naruto was able to surpass him: Sage mode, a solution to peace and bringing his friend back.

Orochimaru wished to learn all Jutsu, Sasuke already had what he wanted (Sharingan) but also awoke rinnegan and can do essentially whatever he likes.

But Tsunade's main failure was that she wasn't like her grandfather (no wood release for one), and on other grounds (e.g. healing without seals) she figured out her own solution. At no point was there a well-defined point where we could say "hey Sakura clearly surpassed tsunade".
