Boxer Charlie Edwards may be about to take his first shot at a world title, but he is thinking of domination beyond one belt.

The 23-year-old faces defending champion John Riel Casimero at the O2 Arena on Saturday night with an eye on taking his IBF World flyweight title.

Saturday marks Casimero’s first defence in the flyweight division having held the light flyweight title – and it is his double world titles that Edwards wants to more than emulate.

He said: “Being a world champion is not my ultimate achievement, I want to be a multi-weight world champion and this is the first step.

“I am very big for a flyweight boxer, I am 5’7”, the likes of Manny Pacquiao and Floyd Mayweather are 5’7” and they are fighting all the way up to welterweight.

“Who says I cannot do that?”

Edwards added: “Obviously it is one weight at a time and as I grow older my body will develop and I will change my training, put the weight on and get stronger and stronger.

“It is all a case of how far my body and skills take me.”

The public weigh in takes place at the indigo at the O2 Arena on Friday from 12pm, and the fight will be on Sky Sports Box Office.
