Yea, It is pretty important .Long ass way behind she need boobie surgery and breathing exercises before she Tsunade level
Of course the gap is that far, Tsunade is leagues above Sakura.The gap between them isn't THAT far. Tsunade is still worlds above her in general medical ninjutsu, but Sakura's strength and battle prowess are catching up since she can now use the Byakugou. Since Sakura can also summon Katsuyu, there really aren't that many differences between them except that I highly doubt Sakura would survive being cut in half all the while still using her jutsu. She will catch up fairly soon. Tsunade doesn't have that much on her other than superior medical ninjustu.
lol read her fight with Sasori again because you obviously didnt pay enough attention.tsuande will always be stronger because of her bloodline alone. She gets cut in half and lives sakura gets a scrape and she probably die.
I'm guessing that's because Tsunade has Uzumaki blood? Sakura has no bloodline so she will be like Lee is with Guy. Near to surpassing as she ages but never truly an exact copy.Of course the gap is that far, Tsunade is leagues above Sakura.
Sakura doesn't have natural immense raw strength like Tsunade, using chakra enhanced punches. Tsunade on the other hand has all of these over Sakura:
1) Creation Rebirth/Strength of a Hundred Technique
2) Immense raw strength
3) Ranshinshou
4) Senju/Uzumaki Lineage
5) Medical Ninjutsu on a whole other level
6) Boobs.
