Manny Pacquiao still wants to gain revenge over long-time rival Floyd Mayweather, his trainer Freddie Roach says.
Pacquiao will fight Yordenis Ugas for the WBA 'super' welterweight title on Sunday morning from 2am, live on Sky Sports.
Aged 42, the legendary Filipino remains at the summit of boxing and has not given up hope of luring Mayweather, who is retired aged 44, back into the ring.
Pacquiao's Hall of Fame trainer Roach told Sky Sports as quoted by Sports Central: "We would like to fight Mayweather one more time. "But exhibitions? No. Manny is not into that. "Manny has boxing fans. That's what we're after.
Mayweather defeated Pacquiao in the richest fight of all time in 2015 and, since retiring, has returned for exhibition bouts most recently against Logan Paul.
But eight-division champion Pacquiao is still at the sharp end of the sport and was set to challenge the undefeated Errol Spence Jr before his withdrawal, and Ugas' entry.
