Lmao, as its been said by others both sasuke and naruto at that time were jonin level ninja's, naruto didnt have sage mode and sasuke didnt have ms. No way they are winning.
In fact if naruto had sage mode and sasuke had ms, they would still lose without info on pein
Kakuzu is kage level, a low kage, but still kage, yet naruto pretty much ended three of his hearts on his own. Not saying that base naruto would beat kakuzu, but they are at least of comparable strength.
Deidara is also a low kage level, since he was able to beat gaara. Most people will say that deidara's victory was only because gaara was worried about the village and I agree, but what most people don't realized is that gaara had his advantage too: the battle was in a desert. Deidara is at least low kage level as well, and sasuke strait up beat him.
There's no way the duo are beating pain and konan, but saying that they are both just jounin level is wrong.
