WBO welterweight champion Jessie Vargas (27-1, 10KOs) is confident of scoring a knockout victory on November 5th at the Thomas & Mack Center in Las Vegas - when he faces eight division world champion Manny Pacquiao (58-6-2, 38KOs).

Pacquiao retired back in April, when he decisioned Timothy Bradley over twelve rounds at the MGM Grand.

Vargas captured the vacant welterweight belt back in March, after knocking out unbeaten Olympian Sadam Ali.

Vargas wants to continue his run with yet another knockout by blasting out Pacquiao into retirement. Because of Pacquiao's big name and the possibility of a mega-fight rematch with Floyd Mayweather Jr. in 2017, Vargas wants to leave no doubt by scoring a knockout victory or dominating Pacquiao in very clear fashion.

"I will look for the knockout. I know the risks I have... what I mean is that Manny has a name, and I have to beat him clearly or knock him out. I won by knockout in my last fight and I will surely do this again... you have to win round per round and then knock him out, and I really think I will do that with the team I have - because I felt stronger for my last fight," Vargas told ESPN Deportes.

"Pacquao is a fighter with a lot of experience, he's very good. I have to be smart, my style is to attack, but I'm not rough. I will use my intelligence, prepare my attacks, compete with speed and take advantage of my reach. I will be taller and stronger."

"Actually we are working on a little of everything, focusing on my style, how my style can affect Pacquiao, adjusting the speed.... taking a bit of Erik Morales, Marco Barrera, but adjusting my style - and I'm not taking as much from Juan Manuel Marquez or Floyd Mayweather, but we are also looking at [their performances against Pacquiao]."
