Every UFC and mixed martial arts fan knows by now how much of a genius Khabib Nurmagomedov is... especially when it comes to grappling inside the Octagon.He made an entire career out of being a total master on the mat, and that is why he managed to retire from the sport with a perfect record of 29 wins and zero defeats.Now, he's trying his best to pass on that knowledge and wisdom to the next generation, and one person who is reaping the rewards of having the Russian in his corner is Islam Makhachev.The 30-year-old has currently taken to the cage 11 times in UFC, winning 10 of them, with his most recent coming at UFC 267 against New Zealander Dan Hooker.Heading into the bout, Makhachev had only lost once in his professional career, falling to defeat in just his second fight with UFC. Back at UFC 192 in 2015, he lost to Adriano Martins via a first-round knockout.Since then, though, his record has been perfect and his victory over Hooker yesterday is by far his biggest yet.Although he's deadly in the Octagon by himself, having Khabib by his side and in his corner certainly helps him, and that was on full show in Abu Dhabi yesterday.ENTER GIVEAWAYWhilst dominating Hooker in the first round and eventually managing to take him to the mat, Makhachev looked for the submission. In his corner, you could hear Khabib yelling instructions and advising him what to do in order to clinch the victory.In the aftermath of the fight, a video has emerged on social media that highlights the fact the retired Russian was yelling at his fighter to secure his leg round Hooker's head, something that would enhance the strength of the submission lock.Makhachev did just that, and seconds later, Hooker had no choice but to tap out.You can see the clip for yourself below.

Khabib inside the Octagon as a fighter himself was deadly, but Khabib as a coach and mentor provides the opportunity to help several other fighters become just as good as he was.

A very scary thought.
