Kamaru Usman has never shared the mat with Khabib Nurmagomedov and Islam Makhachev despite being close friends with them. Usman is currently rallying for a welterweight title fight against Makhachev. Many believe the matchup is being plotted by their common manager, Ali Abdelaziz. Courtesy of Abdelaziz, Usman is a close friend of Makhachev and his mentor, Nurmagomedov. However, "The Nigerian Nightmare" surprisingly revealed that he never had the opportunity of training with either Makhachev or Nurmagomedov.
