i think it's biggest insult for Itachi to say sakura can get out of that.. i mean... V_V.. and mak3 please don't call sakura genjitsu specialist.. cause she's so not..i do not wanna repeat myself.. so look at pg 3 on resemblence.. if you wanna know why i think that.. actually sasuke kinda is....cause he's usually the one to figure out before any of the teammate does...

and anyways.. yea right.. the day sakura beat Itachi when sasuke, and kakashi can't.. will be the day that the anime title changes to sakura..

EditL genjitsu itself can't physically hurt ppl.. but they can use illusion as advantage to inflict physical damage on the opponent
