WBA "regular" welterweight champion Lucas Matthysse says he is well aware of Manny Pacquiao's reputation of beating Mexican fighters.

Pacquiao, after numerous wins over Erik Morales, Marco Antonio Barrera, Juan Manuel Marquez, Oscar De La Hoya, Antonio Margarito and several others - was given the moniker of “Mexicutioner.”

Marquez is the one of two Mexican boxers to gain a win over Pacquiao - when he knocked the Filipino fighter out cold in six rounds in their fourth bout in 2012. With Morales winning the first of his three bouts with Pacquiao by decision - and Pacquiao winning the next two by knockout.

Matthysse is not bothered by Pacquiao's feared reputation that was built on his vicious wins over Mexicans and fighters from other Hispanic countries.

“Yeah, I know that [he's called the Mexicutioner]. I know he’s great against Mexicans, but I’m sorry to say that he has yet to fight and win over an Argentine,” Matthysse said.

Oscar De La Hoya, the CEO of Golden Boy Promotions and promoter of Matthysse, expects a lot of drama in the fight.

He's advised Matthysse to come forward and make things happen.

Pacquiao, who turns 40-year-old at the end of the year, is coming off a one-year layoff and a shocking twelve round unanimous decision loss to Jeff Horn in Brisbane, Australia.

Pacquiao has declined over the last few years and most believe this contest is all or nothing for him - with another loss a sure nail in the coffin of his career.

Win or lose, Pacquiao has been very happy with his career - with had a record breaking eight world titles in eight weight divisions.

"I have always been a boxer. Boxing has been my country's (Philippines) source of pride and my humble contribution to my fellowmen. When I won one world title after another until we had 10 world titles in eight divisions, it felt like we have won the World Cup many times over," Pacquiao said.
