Jinbe vs Pizarro also could happen, sea vs land. Pizarro favorite food is also shark fin soup.
I began leaning into OG's Straw hat + Chopper will fight OG Blackbeard's + their sixth ranger, Shiryuu.
While Impel Down gang will fight Straw Hat later members.
That put Sanji as Burgess opponent, as long it's done correctly (make Burgess looks threatening enough) would be fine.
Martial arts Speed vs Strength stuff, Burgess goofy personality also makes sense since Sanji opponent usually goofy arrogant dude (Mr 2, Jabra, Queen)
The fight will certainly include the usual Sanji trash talking his goofy opponent.
