Naruto Itachi vs Sasuke?

So who do you think will win?

Before the time slip I could say without a doubt Itachi.

Sasuke had to grow stronger. So him leaving with Orchimaru was a good choice.

After the time slip unless Sasuke can pull something out of his bag of tricks then Itachi.

Unless Itachi has lost his eyesight then Sasuke.

Spoiler: Team Sasuke

They won't do much against Itachi Sharingan. I believe their purpose more lies in taking out Kasumi.

Spoiler: Number 1 reason why Sasuke can't beat Itachi

He could barely beat Deidara. Deidara ended up blowing himself.

So unless Sasuke gets more training or has a whole bag of tricks then no.

Maybe he will get lucky and Itachi will go blind.

So for now I don't think he can beat Itachi up.
