Legit don't understand the logic behind Sanji vs Kizaru.
There is absolutely no set up what so ever, Sanji is never portrayed to have serious conflict with Kizaru.
Kizaru has affinity to go after first mates, like Rayleigh, Beckman and Marco.
Oda specifically focused on Zoro when it came to Kizaru where symbolism was off the charts with first mate of future pirate king being saved by first mate for former pirate king only for Kizaru to reveal that his preferred CqC style is swordsmanship.
EoS Zoro vs Kizaru actually has some implication, EoS Sanji vs Kizaru literally has zero basis.
