Naruto arguably has an infinite amount of chakra--the juubi's chakra is infinite and the nine bijuu equal the juubi, it was just divided into nine parts.
Can you imagine if there were a thousand sage naruto's each with an infinite amount of chakra with the speed of a Juubi jin? We won't even get into his destructive capabilities.
9 onymoudon orbs times 1000 naruto's? He'd rape anyone and there's nothing shown so far proving otherwise
If Naruto and Sasuke are equal at this moment, then theoretically 1 naruto + 1 clone > Rinnegan Sasuke
or is rinnegan Sasuke equal to three Narutos? Cause then 1 naruto + 3 clones > Rinnegan Sasuke.
We just need to see more of this fight to make any assumptions
