"One Piece" chapter 781 spoilers may have been revealed online as it is suggested that Sabo would fight Trebol as Luffy finally hits Doflamingo with a good shot.

KpopStarz gave a short summary of the previous "One Piece" chapter:

"Donquixote Doflamingo and Trebol remain as the only members of the Donquixote family. Luffy just knocked out Bellamy and it is currently unknown if Trafalgar Law is dead. A short flashback was shown where Law still managed to mock Doflamingo which resulted to Law being gunned down. As Luffy arrives in the scene, he attacked Doflamingo but to no avail. He stumbled upon Law soaked in blood which made him mad, but at the last page, it is uncertain if Luffy remembered something Law said or Law actually talked to him," wrote KpopStarz.

And now, Manga Mugen has revealed some "One Piece" chapter 781 spoilers when he noted that Sabo would fight Trebol and speculated that Sabo would actually have a hard time fighting Trebol.

"Sabo is rushing to where Luffy is after Koala told him so...Either way I don't see Luffy being able to take on both opponents, or he will meet the same fate as Law. So while I'm not too happy that Sabo is going to face Trebol I have to admit it's the most logical conclusion. Also it's possible that Sabo cannot take down Trebol as easily, maybe because he hasn't mastered his DF," wrote Manga Mugen.

A Reddit user has also stated that Usopp would be help with the fight as he would be instrumental in beating Trebol and helping Luffy get the jump on Doflamingo.

"Law quietly gets his last words/bad-ass speech about how Luffy will change the world and how he can't let people like Doflamingo get there way. Doflamingo and Trebol laugh and start to attack Luffy together. Usopp shoots Trebol with fire making him explode, surprising Doflamingo. Luffy proceeds to deck Doffy in his smug face, making him spurt out blood from his mouth," wrote the Reddit user about "One Piece" chapter 781 spoilers.
