Okami has respect for his UFC Fight Night 28 opponent, but he still expects to dominate the fight and walk away with a victory.
"I'm going to utilize all of my MMA techniques, and I'm going to wear him down and I'm going to smash him," Okami told Bleacher Report.
Okami thinks a win over Souza will help him climb back towards the top of the middleweight ranks, to a spot he hasn't been at in years.
"Of course my goal is to become the top (fighter) in this division," Okami said. "So, I'm not satisfied with my ranking right now. If I beat Jacare, it's going to be a big step up for me to prove that I'm the No. 1 fighter in this division.
"By beating Jacare I'm going to be given that kind of right, but it's not only important to win, but how I win the fight. Always, I'm going to fight whoever the UFC wants me to fight."
Okami admits he's going to be careful how he attacks Souza if the bout goes to the mat.
"Jacare is not just a jiu-jitsu fighter, he's a specialist at jiu-jitsu," Okami said. "I am really careful about how I fight him in the ground fight, but I'm not afraid of fighting him on the ground."
Okami isn't sure why he's considered an underdog against Souza, since he's a world-renowned UFC veteran.
"I have no idea why people are thinking that way," Okami said when hearing about the odds. "I really do not care what people are talking about.
"I know that Jacare is a great athlete and a great fighter so he deserves that consideration. To me it's a great honor to fight against such a great fighter."
