Before DJ:
Not only a serious Jyabura outright overpowered Sanji in every clash they had, but Sanji couldn't even react to Jyabura's sheer mobility and attack speed.
Even after DJ, Sanji could not tag Jyabura to land a second, finishing hit, and needed to be hit by an attack and take decent damage just so he could land his own attempt:
Nothing downplay. Sanji was getting overwhelmed in speed, strength and literally everything until he used DJ- and even then he was not fast enough to land a hit and needed to bait just to finish. Scans above.
Also lmao @ thinking a fodder like Khalifa got Sanji "extremely injured"
