WBC welterweight champion Shawn Porter has zero interest in avenging a 2014 decision loss to Kell Brook and there is equally little interest in having a fight with Bolton star Amir Khan.

This Saturday night, Porter will take part in the biggest fight of his career when he collides with IBF welterweight champion Errol Spence at Staples Center in Los Angeles, California.

"Would I want to fight Brook again? I don't think so. His career has gone off in a totally different direction to mine after he beat me, and I don't think me beating him now and levelling things up would bring a whole lot of credit. He's been beat by GGG and then he lost to Spence, and I don't even think he has anything lined up at the moment," Porter told Sky Sports.

Porter admits that at one point he was interested in facing Khan - but that is no longer the case.

"Khan was a great fighter, and a fight between me and him a couple of years ago would've been certain to get people talking," said Porter.

"He's still about now and he's doing okay for himself, but he doesn't have anything I want at the moment."

If Porter, who is the betting underdog, would defeat Spence and then have his pick of the litter - he would want a showdown with WBA world champion Manny Pacquiao in 2020.

"The fights that matter to me are the ones that will make me the best welterweight on the planet, and that starts with Errol Spence in my next fight. After that I'd like to take on Manny Pacquiao."

"Boxing for me right now is about looking at the guys in my weight class who can get me motivated and want to get in the gym and give my all every single time. Errol Spence is a fighter that does that for me and that's where I want to be at."
