Minato's main way of engaging an opponent is by throwing his marked kunai and teleportating to it. Since in this versus Itachi has full knowledge of this ability, he can repel Minato's thrown kunai's with his Shurikenjutsu. With Minato's teleportation feat being countered, that leaves only his usage of the Body Flicker Technique to confront Itachi head-on, but speed attacks can be countered by the Sharingan.

Itachi can effectively counter Minato's fighting style without needing to waste chakra on genjutsu or activating his Mangekyō Sharingan, while Minato is essentially helpless if he is caught in genjutsu.
