Re: Itachi vs. Minato
Wow, you sir vastly underestimate Itachi. Itachi said that about Jiraiya because he actually still cared about Konoha, not because he was scared. Also he never said Jiraiya would beat him and Kisame easily, you don't read the manga do you? He said the best he could do would be a draw. Which was him just saying stuff to get out of there because he didn't really want to capture Naruto.

Now that I have corrected your mistakes, I'll explain to you situations in which they both could win. Minato would win if Itachi didn't automatically put up Susanoo or if Minato managed to tag him with a seal before he put up Susanoo. Minato also has way more chakra than Itachi so he could always just run around or teleport around until Itachi ran out of chakra or went blind.
So Minato wins the majority of the time, however Itachi would win if he managed to trap Minato in a genjutsu at the start of the battle, especially if he got him in Tsukuyomi. If it is just a normal genjutsu then Minato probably could break out of it but dispelling genjutsu isn't instantaneous so Itachi would have time to kill him.
So if Itachi starts off with a genjutsu that Minato can't break out of quickly, or if Minato looks him in the eye then Minato loses, any other way and Minato wins this battle.
