For that piece of discussion we actually need the Episode 606 - NWTChuu.
I didn't foresee Sanji fighting this guy, but I suppose it makes sense with Vergo being an unarmed fighter, by the looks of it. Although I'm still not sure he doesn't have a fruit power of some sort. Tings sticking to his cheek might suggest something, but who knows. I can't help but wonder who's Zoro going to fight, if anybody. Luffy at the very least is facing Caesar again and I doubt he would want assistance in the fight. That leaves very few potential opponents unless the frozen dudes suddenly thaw (not that unnamed opponents would still make very exciting opponents). Not to mention we still have Law hanging around as well. This looks a bit asymmetric. Usopp should fight Monet for a while; he seemed so scared of her back then.
Actually, Zoro should fight Tashigi. Just for the laughs. I wouldn't expect Captain-chan to last very long, but such a scene might present some comedy and good lines.
