What are you saying?Doubt it. If people believe Shin could beat Naruto & Sasuke together surely there's no way Sakura even stood 0.0000000034% of a chance.
Sakura has regeneration techniques that are instant and knife implement isn't enough to negate them.

1st Classification: Ninjutsu
2nd Classification: —
Main User(s): Tsunade, Sakura Haruno
Class: Supplementary
Range: —
Rank: S-Rank
Heading: —
For several years using the highest most precise Chakra control(BM user have the best chakra control), a fixed amount is stored in the Byakugō seal. The Chakra is usually put to use to regenerate the body through the technique Sōzō Saisei, the combination results in the ultimate regeneration technique.(BM>Juubi Jin in regeneration)
The seal was able to regenerate the body, despite Tsunade's Chakra quantity being less, than the enormous Chakra quantity of the First Hokage.
When Ninpō Sōzō Saisei is used at the same time as Byakugō no Jutsu, it becomes possible to use it (Sōzō Saisei) over a long period of time. When ones life is effected by grave wounds pushed to the point where they'd normally die, ones body is instantly returned to an unwounded condition.(Instant regeneration)
↑→ Release the Chakra stored in ones forehead. Wounds completely recover, while at the same time ones own power rises, however cell division quickens, which shortens ones life span.

Yin Seal: Release* (陰封印・解, Infuuin: Kai)
Fuuinjutsu, S-rank, Supplementary
User: Tsunade
Unravelling the key to using the “Genesis Rebirth”**!!
“Genesis Rebirth,” the ultimate medical technique. However, using this technique requires such an enormous amount of chakra, that it is beyond any shinobi to mould it in an instant. Tsunade, using the chakra stock kept in the seal on her forehead, has cleared this prerequisite. With “Yin Seal: Release,” the seal is released, becoming the source for the body regeneration technique.

↑The moment it is unsealed, a pattern appears on the forehead.

←Releasing the seal is the greatest danger signal.
*Kai (解) literally means “untie,” “unravel”.
