We all suspect that Sasuke needs a major power-up, if he wants to fight with Naruto, and doesn't want to be stomped.
Oro was commenting that it did bother him a little... Naruto's chakra.
I think Oro didn't mind it so much to be in Sasuke last time... perhaps.
Please... Don't let Sasuke's power-up be Oro, again. It would make the brat instantly number 1.
