Islam Makhachev may have become a two-division UFC champion, but Daniel Cormier still holds one unique record that the Dagestani grappler can't break.Makhachev defeated Jack Della Maddalena via a dominant unanimous decision in their welterweight title fight at UFC 322 last weekend in New York and became the 11th fighter in promotional history to become a two-division champion. He is also tied with Anderson Silva for the longest win streak in UFC history, with 16 consecutive wins on his record.Given Cormier's close relationship with team Khabib Nurmagomedov and Makhachev, it appears there has been some friendly banter among them regarding UFC records. Cormier is a former two-division UFC champion and is widely considered among the greatest fighters ever.In a short post-fight clip from the Anatomy of a Fighter documentary series, Cormier, Makhachev, and Nurmagomedov can be seen enjoying some food while discussing UFC records. During their chat, Makhachev can be heard asking Cormier:"One question, what record do you have that I haven't beaten?"Nurmagomedov promptly replied:"He defend in both [divisions]."Cormier then reminded Makhachev why his record of having successful defenses in two different divisions while simultaneously holding both titles can't be broken:"Same time, [I defended at the] same time. See? And guess what? They don't let that happen anymore, so I'm safe."Daniel Cormier on potential Islam Makhachev vs Ilia Topuria superfightIn June, Daniel Cormier shared his thoughts on a potential Islam Makhachev vs. Ilia Topuria fight and called it one of the biggest that the UFC could book. Makhachev and Topuria have notably traded shots online, with both fighters keen on throwing down in the cage.In a video shared to his YouTube channel, Cormier previewed the scope of a Makhachev-Topuria fight and said:"Obviously, we know that there are some big fights in the UFC. I don't know that there's a bigger fight that the UFC can make, that's going to be bigger than Topuria and Makhachev, if they are to fight."He continued:"Ilia Topuria is a massive favorite over everyone in the UFC except Islam Makhachev. And that in itself tells you what people think of Islam because of how highly regarded Ilia Topuria is right now, especially after becoming the UFC lightweight champion in the fashion that he did against Charles Oliveira."
