LOL, I just had a very strange theory popped into my head.
Inner Sakura will defeat Itachi.
Its simple, Itachi attacks Team 7 while there doing some mission, Naruto and Sasuke are out of action due to Itachi's shranigan..and then tries to use it on Sakura but instead Inner Sakura suddenly appears inside of Itachi's mind and crushes him. LOL...I better get some sleep now.
