Let's be honest here, Itachi isn't losing to full powered Rinnegan Sasuke!

[Im Still Robin]

Dude with 1 vs 1 with naruto and his rinnegan wasn't even trained.

I'm pretty sure he solo's either way.

Itachi is just like Ace of the NU, its really annoying.

Sasuke > Itachi

Luffy > Ace

 

[Shruikan]

Any form of Sasuke Above 3T negs Itachi effortlessly

 

[Solo Arrow]

Only itachi fans think he can beat sasuke. itachi was surpassed a long time ago
