ok so itachi has everything he has learned and also has no disease. naruto can use anything he has learned. they both have the intent 2 kill who wins
but naruto has knowledge on genjutsu so its not like naruto is just gonna stand there and look at his eyes and wait for itachi 2 put him in a genjutsu plus he is fast when in chakra mode so it will be very hard 2 put him in genjutsuitachi he would just get him in genjutsu and it would be a rap
