Former two division world champion Timothy Bradley believes Teofimo Lopez has nothing left to accomplish at the lightweight limit of 135-pounds.

He would like to see Lopez move up in weight to challenge the winner of the 2021 junior welterweight unification between Jose Ramirez and Josh Taylor, who will battle for the WBO, IBF, WBA, WBC titles.

Lopez, at only 23-years-old, pulled off a history making win last Saturday night at the MGM Grand's Conference Center in Las Vegas, when he won a twelve round unanimous decision over Vasiliy Lomachenko to unify the WBA, WBC Franchise, WBO, IBF lightweight titles.

There are lucrative opponents at lightweight - like Ryan Garcia, Gervonta Davis and Devon Haney - but Bradley believes Lopez already beat the top guy at the weight and now it's time to invade 140-pounds.

"He's done at 135. He beat arguably the best pound-for-pound guy in the world at 135 and he took all the straps. He has no business left at 135, and he doesn't have to struggle to make that weight anymore. He has the ball in his court now. It's time to go up to 140," Bradley told ESPN.

"Lopez has to continue to challenge himself. He just fought arguably the best fighter in the world. Where do you go from here? I'm not going to say I'm a mad genius, but I'll just put it this way. He's already been a part of a historic event. If he wants to be a part of another one, there's two fighters at 140 that are going to be unifying the titles, likely at the beginning of 2021.

"Why not go after the winner, whether it's Josh Taylor or Jose Ramirez. Top Rank has both of those guys under their promotional banner, and the fight can easily be made. So you'll have the undisputed 135-pounder (or unified champion, depending on how you want to put it, because Devin Haney was basically handed his title) versus the undisputed at 140 pounds. He will move up and he will face the undisputed champion at 140."
