Borsalino's opponent from the Strawhat crew is Zoro not Sanji. There are a few reasons to expect this to be the case:
As far as I can tell, the main reason to expect Sanji to be Borsalino's opponent is out of some mistaken belief that Borsalino specialise in kicks/has a kick based fighting style. However, this is a gross misunderstanding of his actual fighting style. Borsalino has literally only ever used his kicks to troll characters that were fodder to him:
Someone might counter that Issho is Zoro's Admiral opponent, but this looks unlikely given that:

- Borsalino used a sword in his only serious fight against another top tier
- He has a named techniques for creating said sword "Ame no Murakamo".
- Said sword is one of Japan's sacred imperial regalia
- He is proficient enough as a swordsman to completely stalemate a top tier "pure swordsman" like Rayleigh
- He's repeatedly been paired in battle against the second strongest fighters of a pirate crew
- With Rayleigh at Sabaody Archipelago
- With Marco at Marineford
- With Benn Beckman at Marineford
- Borsalino has unresolved conflict with Zoro
- He easily defeated him at Sabaody Archipelago
- He commented that Zoro must have already been weakened to go down so quickly
- A future confrontation would resolve this.
- Borsalino and Zoro seem to occupy similar positions.
- Borsalino is Sakazuki's strongest subordinate
- Zoro is Luffy's strongest subordinate

Someone might counter that Issho is Zoro's Admiral opponent, but this looks unlikely given that:
- Issho has a more fleshed out conflict with Luffy
- Issho appears to be a Luffy fan
- Issho may not remain a soldier for the World Government at the final war
