It sounds like Manny Pacquiao isn’t going to fight again until 2020. Pacquiao returned to the Philippines to continue to fulfill his obligations as a senator, after an impressive win against Keith Thurman. Probably he won’t return to the ring until after he turns 41 in December.
And the most sounding name that might be a candidate of his next opponent are Errol Spence, Terence Crawford and, hmm, Floyd Mayweather Jr. Though Thurman mentioned a possible rematch on Saturday night, there’s not much reason for Pacquiao to take that, and it's Pacquiao with the team to decide.
It’s unclear who Pacquiao will get next. But I’m in saying this: "It probably won’t be Mayweather". Just my wild opinion.
