Tsunade can beat 10 ninja ..

[kooko]

You say it'll be a piece of cake against Zabuza and Sasori.....she would beat Zabuza but lose to Sasori

Zabuza is strong as jounin but she's kage level that's why he will lose ..

If sakura beat sasori then it will be easy for tsunade ..

She can't beat Nagato, Tsunade has no counter to a simple Shinra Tensei.
She can't beat Madara, simple Shinra Tensei.
She can't beat Minato, he's too fast, and Tsunade isn't exactly a speed type.
She can't beat Itachi, since we haven't seen her counter genjutsu before.
She can't beat Sasuke, since he can spam Amaterasu now.
She could beat Sasori, since she pwned Chiyo back in the day.

U a trolll, Tsunade is weak
