Everybody hates Sasuke!
Neji>Sasuke...

Neji beats Lee. THat means, Neji can cope with Lee's speed (right?)

Fireballs.. Ah, they would just bounce of Neji.

Chidori.... Can he hit Neji in the first place?

Even if Sasuke can predict what Neji is doing or about to attack, he can't see the chakra points, thus, Sasuke can't learn Neji's attacks.. none whatsoever.
