The 25-year-old lightweight came into his ONE FC: Warrior's Way fight as the underdog, but his knockout victory over Eduard Folayang at the SM Mall of Asia Arena became one of the talked about MMA moments of 2014.
The Russian said: "I just entered the cage and followed my gameplan. I did not plan this knee, but I noticed some defensive movements of my opponent and try to catch him with knee. As you see it was a good action.
"I am happy that my fight was highly regarded by the MMA world and I will continue to delight my fans with spectacular fights because I love the ONE FC rule set.
"I was excited to fight for ONE FC, not just about my opponent, but we took it serious and made a lot of work with my coach on Eduard so when I got the KO it did not surprise me."
Nastyukhin added: "I always dream about fighting in world-class promotion and when ONE FC sent me the contract it was as my dream come true, so I am planning to make a lot of fights here."
