Islam Makhachev (19W-1L-0D) has been built (profile-wise) as an heir to Khabib Nurmagomedov's throne. Khabib (29W-0L-D) has defeated every single opponent he has faced as a professional MMA fighter and recently decided to retire. Many consider him as the GOAT (Greatest of All Time) in MMA. Islam has decent striking and can hold his own standing up, but his ground game is just incredible. Coming from a combat sambo background (multiple time world champion), being exposed to high-level wrestling in his homeland of Dagestan ASSR, and just growing up training with Khabib Nurmagomedov, he seems unstoppable on the ground. Standing up is where he got his only loss: getting TKO'd in the first round by Adriano Martins (28W-10L-0D) in 2015. He overcommitted with a lead hook, exposed his chin, and got caught by a counter lead hook. At 26 years old, Tiago Moises (15W-4L-0) is three years younger than Islam (29). However, both guys are very young, so age is not necessarily a factor for their physical preparedness. Tiago is a black belt in BJJ. Islam is the heavy favorite to win this fight.
