I just said what if Minato uses ftg and instantly kills him.
I won't use what ifs but that means Itachi doesn't know anything about a man popping out of a kunai within .0000000000001 of a sec which means he won't know to use susanoo. So I just proved u wrong and if u still think Itachi wins then ur just a fanboy since u have no reply to the bold part. Another thing, Minato wud easily dodge amatarasu, hes faster than A. U are overrating amatarasu's speed, its not that fast, look Sasuke almost ran away from it.

Amatarasu travels! How did Minato have the reflexes to see A's fastest punch coming who is faster than amatarasu??
How did Sasuke run away?
Face it, ftg means Minato has more of a chance to win this.
