Manny Pacquiao's team is ALL IN for a rematch with Floyd Mayweather -- so says his trainer, Freddie Roach who tells TMZ Sports, "I really think Manny can knock him out."
After 40-year-old Manny put a hurtin' on Keith Thurman this weekend, there's a huge buzz about a MayPac II rematch ... following the first superfight back in 2015.
Roach, who's been training Pacquiao for years, says Manny and the entire team is down ... if Floyd is man enough to get back in the ring.
"[Floyd] would be a fight we'd want. I'd like to get that one back one more time. I know we can do much better. We had an injury in that fight, but regardless, we lost a close decision. I know Manny can do much better than that."
Remember, after their May 2015 fight, Manny revealed he suffered a shoulder injury in training camp which he says held him back in the main event.
But now, Manny's healthy -- and looked awesome in the Thurman fight -- and Roach ain't all that impressed with the work Mayweather's done inside the ring over the past few years.
