French-Cameroonian boxer Carlos Takam believes Joseph Parker's unification title bout against Anthony Joshua will be a battle of speed against strength.
The highly-anticipated bout will take place at the Principality Stadium in Cardiff on April 1 (NZT) and will see Joshua and Parker put their IBF, WBA Super, IBO and WBO belts and unbeaten records on the line.
Takam has fought and lost to both Parker and Joshua during his career and believes Parker's speed will be the key if he is to trump the Brit.
"Joseph Parker, the guy has speed, a lot of speed. I think his speed is faster than Joshua," Takam told Sky Sports UK.
"Joshua is strong, but Parker's speed is faster than Joshua and we're going to see what is going to happen in the fight - speed or strength.
"For me, those two are the best. I have respect for Parker, I have respect for Joshua. For me, they are two good fighters, two good boxers, two good champions."
The 37-year-old Takam admitted he will be in attendance for the fight in Wales and that he would like to face Englishman Dillian Whyte, who is facing Australian Lucas Browne next month.
WBC Heavyweight champion Deontay Wilder had very similar thoughts to Takam's which he shared in an interview with RadioLIVE's Sunday Sport.
"Parker will also have to be mobile which I think he will do a pretty good job of. The things I'm telling you now I've told him before because we talk.
"He is going to have to continue to punch while he moves and keep his head moving. If he can do that, he will see openings and see some of the weakness Joshua has."
Wilder will likely face the winner between Parker and Joshua later in the year.
