Francis Ngannou is already looking beyond his big fight with Anthony Joshua and has set his sights on a meeting with Deontay Wilder.
The former MMA star has made a comfortable transition into boxing, impressing in his defeat to Tyson Fury last October, and will clash with Joshua next month in Saudi Arabia.
However, the 37-year-old has already targeted his next fight and wants a showdown with Wilder, despite the American's stock falling after his defeat to Joseph Parker.
"I'm here for the boxing career and there I have a lot of challenges, a lot of names. For example, the top three guys that I've always had are Fury, Joshua and Wilder," Ngannou told Sky Sports' MMA Club.
"Wilder better get it together because I'm not done, I want that name on my record.
"Two months ago, we were talking about fighting Deontay Wilder in the PFL [Professional Fighters League]. The landscape can change quick. Everything is possible."
Ngannou became a MMA legend but spilt with UFC last year and says his focus is now firmly on his boxing career.
"It's a boxing career, it's not an MMA career now. We are here talking about my boxing career," he added.
"In my MMA career, I got to the point that is everyone's dream. I was MMA champion. There are some great fights to do in MMA but there's not a new challenge, something exciting in MMA."
