@Dizmiz, well, at the time Naruto offered to go he had half of Naruto's full chakra (which includes any power from the Tailed Beasts that he had) so yeah, I'd say Naruto had enough chakra.

In any case I'm not sure how much chakra that technique takes in the first place. Of course I'm not downplaying Nagato, he performed an insane feat there.

Sakura's chakra was stored for three years continuously. Tsunade had been using hers throughout Shippuden. There's probably a difference in their Seals' power at that point. Tsunade was of course more skilled with the tech in general, but I think Sakura had more chakra actually in her seal.

So yeah, Sasuke being able to travel dimensions already gives him way more than half of Naruto when Naruto had the chakra gift from Hagoromo and the full Tailed Beasts Cloak. I think Sasuke has a sizable pool of chakra.
