Well Taijutsu wouldnt be a choice 4 itachi so he'll have to resort to Genjutsu (Clones Tsukyomi) Raikage has no defense against genjutsu, especially not 1 at itachi's level, so itachi ftw
Raikage, look what happened to Sasuke. Susanoo went to his head and almost got him killed. He also can easily dodge Amaterasu and with his incredible speed he can move past Tsukuyomi. The only way Itachi will probably get him with Tsukuyomi is pointing a finger, and i think he's fast enough to be pointed at with a finger (REALLY....LOL).
Alot of you say itachi but iSay Raikage. First Raikage can defelct itachi's genjutsu cause he did sasuke's cause of his lightning armor. And the raikage is much more faster than itachi. And iDont think the raikage is dumb and reckless.
