Nathan Cleverly insists that Badou Jack’s inexperience as a light-heavyweight will be his undoing.
WBA 'regular' champion Cleverly makes the first defence of his belt this weekend on the Floyd Mayweather-Conor McGregor undercard against Jack, who is stepping into a new weight division after reigning as WBC super-middleweight title-holder.
"He's an established world-class fighter," Cleverly exclusively told Sky Sports. "He does the basics very well. He's very solid on the world stage.
"But he's moving into the light-heavyweight division now. He says he'll have more energy and be stronger, and possibly so. He may feel invigorated at the new weight. But he's coming up against an established light-heavyweight on the world stage. This is my eighth world title fight.
"He's going to see the difference at some point. It's going to pay dividends.
"I'm going to deal with him in a good fashion. I believe this fight is a good fight for me to move onto the elite level. This is a world class fight but the winner can move onto the elite level.
"I'll have too much for Badou Jack. I believe I'll out-box him and have too many ring smarts, and win a convincing decision."
Cleverly won the WBA 'regular' title in his last fight against Juergen Braehmer, while Jack is coming off a draw in a super-middleweight title unifier with James DeGale.
