Stephen Thompson says he now needs the same mindset he had during kickboxing fight

Stephen Thompson has lost his last two UFC fights, and at 39 years old needs to change something if he plans to become a champion before retiring. In the video above, 'Wonderboy' said he was motivated due to the situation with his opponent, his dad's instructor, and his sister. During the same video, Thompson had this to say about needing to bring that mindset back: "Watching this fight, it fires me up. I gotta get back to this kinda mindset. I just went through puberty, so I had that new sense of testosterone flowing through my body. I was relentless, nonstop, after this guy. That's how I used to fight as an amateur." Thompson is now No.7 in the UFC rankings. With few contenders available, it would likely only take him two wins to earn another title shot. Only time will tell if 'Wonderboy' can pull off the underdog story, similar to Glover Teixeira.
