He doesn't need to destroy the top buddha or even defend from it, he can evade it. Being as he was Hashirama and Tobirama's disciple since Konoha's creation(Hiruzen was ONLY 5-6 years old when Konoha was built and the two Senju brothers noticed how much of a prodigy and genius he was and took him on as their disciple.. even deciding that he would be the 3rd Hokage as they were grooming him as such) he knows the two brothers, their power and techs and all. He boldly claimed he would be just fine and that he was stronger than all of the people there when he said he would be the decoy, Tobirama didn't make a peep to contest his statement at all and only the hateful and jealous Danzo said something.

Hashirama died 34yrs before Naruto was born, Tsunade was born 38 years before Naruto was born. So he did know her.
