are you kidding me, before getting susanoo kakashi could defeat him you dont just underestimate a guy who took out a big part of seven swords man of mist one of them the strongest there was, he defeated the asura path as well, unlike sasuke with cursed seal kakashi didnt have a extra boost, if his sharingan drained him like it would do to an uchicha kakashi could have fought sasuke even with his ms but with ems sasuke has officially become stronger than kakashiwhen he defeated Naruto.in part one .. ?
