I'm just gonna wait for a few chapters until we even have confirmation of this being a true matchup.
Like:
- Alabasta and Enies Lobby had Usopp facing Mr. 2/Jabra first, both Sanji's opponents
- Nami initially fought Kumadori at Enies Lobby
- Sanji initially "fought" Kalifa at Enies Lobby
- Many people fought Diamante until Kyros was the one who actually faced him.
- The amount of encounters Doflamingo had with many people before Luffy is ridiculous
Let's wait before we assume this is going to be a full blown fight with a conclusion, even if it takes 20 chapters
