In the latest episode, in which Sakura is in, "Medic Ninja In Danger". (Not a filler)
Sakura proves to us that she has overcome the training that Tsunade had given to her in the past.
She already knows how to evade enemy attacks, sense when an enemy is near her, attack at the right moment, when to not keep her guard down, and etc.
Furthermore, I believe that all she has to do now is learn some kick-azz genjutsu.
