American boxing legend Floyd Mayweather Jr. is rooting for no less than Errol Spence Jr. over his former rival Manny Pacquiao.
In an ambush interview with the media ahead of his fight with Youtuber Logan Paul, Mayweather vowed to stand behind his people first.
"I wish nothing but the best, both. Both guys," said the 44-year-old Mayweather. "Of course, I'm behind Errol Spence a hundred percent. I'm behind my people first always so of course, I wanna see Errol Spence win.
"Actually, I'm gonna call him and give him some pointers," added Mayweather, who owns a 50-0 record on top of 27 knockouts.

"Absolutely that's my people, I'm gonna always stand behind my people first. Just like the Philippines stand behind Pacquiao. I'm American, I'm gonna stand behind my people first."
Pacquiao and Spence, who is the unified WBC and IBF welterweight champion, will clash on August 21 in Las Vegas but the final venue has yet to be announced.
Pacquiao, who holds a 62-7-2 record with 39 KOs, got stripped of his super WBA welterweight belt and was declared "champion in recess" due to his inactivity while the 31-year-old Spence remained unbeaten in 27 matches with 21 KOs.
