Dude i couldnt care less. Old hiruzen isnt beating A, to use what was said in part 1 as the base for your argument isnt much.
A would win this with low difficulty.
If sasuke who not only has the sharigan on his side, youth and speed and yet he couldnt keep up with A and got liger bomb, which if it wasnt for susano he'd be dead but due to A's speed had to mold amaterasu around susano, what can old hiruzen do.
A would blitz him and liger bomb the old fart, with this snatching the light out of his eyes
