Jessie Vargas is feeling confident ahead of his November 5th bout against former eight-divsion world champion Manny Pacquiao in Las Vegas.
The Filipino legend has come out of retirement to face the American, who will defend his WBO world welterweight championship belt in Sin City.
Vargas believes he has spent his whole life being the underdog and has notched up an impressive 27-1 record, with ten wins coming via knockout.
"I've always been the underdog," the 27-year-old told TWC News San Antonio.
"They always wanted to take me down. They never believed in me and look at me now, two-time world champion, and I will beat Manny Pacquiao because of all of that.
"I use all that negativity…that I won't make it, that I won't win. I grew up that way, unfortunately. Fortunately and unfortunately, you know what I mean? People doubted me all the time. But I always proved them wrong."
Meanwhile, Pacquiao, whose return to the ring seems purely a financial decision, has been training at home in the Philippines in between his sessions in the national congress.
