5 best undefeated champions outside the UFC right now

#4. Anatoly Malykhin – ONE interim heavyweight champion

Anatoly Malykhin may not be the most well-known fighter, but he will be in a matter of a few years. The Russian boasts a perfect professional record of 11-0 and he's the only fighter on this list with 100% finish rate. Out of his eleven career wins, eight have come via KO/TKO and three by way of submission.

While UFC heavyweight champion Francis Ngannou is one of the most dominant heavyweights in the world right now, ONE Chairman and CEO Chatri Sityodtong is not particularly impressed with 'The Predator'. Sityodtong argues that Ngannou is a one-dimensional fighter and isn't very well-rounded, unlike Malykhin.

Earlier this year, Malykhin became the ONE interim heavyweight champion following his win over Kirill Grishenko. He is expected to fight for undisputed gold later this year when he takes on reigning ONE heavyweight titleholder Arjan Bhullar.

#3. Yaroslav Amosov – Bellator welterweight champion

Among the most underrated fighters in the world outside the UFC is Bellator's welterweight titleholder, Yaroslav Amosov. The Ukrainian has enjoyed a scintillating rise up the ranks to become a world champion, and looks set to reign over Bellator's 170-pound division for a long time to come.

The 28-year-old boasts a perfect professional record of 26-0, comprising nine knockouts and ten submissions. He is still a few years away from reaching his prime and it's scary to think how much further he can push his unblemished pro record. With his wrestling prowess and incredible durability, he remains a tough stylistic matchup for most fighters.

Watch a compilation of Yaroslav Amosov's highlights below:

Amasov's UFC counterpart, Kamaru Usman, is hailed by the majority of the MMA community as the best pound-for-pound fighter on the planet actively competing. The two fighters are very similar, and there's an argument to be made that the older, injury-riddled fighter in Usman would struggle against Amosov if they locked horns today.

A potential bout between the welterweight duo would determine the best 170-pound fighter in the world right now, as both champions are seemingly unbeatable in their respective promotions.
