Hahahahahahahahaha you must be hating the fact that itachi is soo superior to every ninja you put him up against
3rd hokage personally knew all the hokages and he finks itachi was on there level age 7 :p
on his own he managed to do what a whole clan of senju couldnt do .
and countless more shinobi
and yes minato would of got owned if they fought
so would obito if he was aware he wasnt madara
