"Joshua is having a fight against Parker, and Parker is a very good boxer. He has fast hands, his punches have strength and they are not inferior to Joshua's. Anthony should not neglect his closest rival. Of course, the style of combat is very important in boxing, but do not forget about the mood.
"If Joshua beats Parker, he and Wilder can make a big fight for $250 million. So why not do it, if there is an opportunity to earn such money? Who knows where Joshua will be at some point? His opponent Parker is an excellent boxer. He has great skills and abilities," Holyfield said.
Joshua and Parker will fight on March 31 in Cardiff.
