5 ONE Championship MMA fights you should see

#2. Vitaly Bigdash vs. Igor Svirid - ONE Championship: Tigers of Asia

Former ONE middleweight champion Vitaly Bigdash debuted in ONE Championship in the best way possible. He won the belt in one of the greatest fights the sport has ever seen.

Bigdash, who fights this December 17 at ONE: Winter Warriors, fought then-champion Igor Svirid in a fight that had more thrills than a Rocky Balboa movie.

Just the fact that this two-round fight had a total of five knockdowns makes it a rarity in the sport. Four of those knockdowns were suffered by Bigdash himself, who had to fight through the unrelenting blitz by Svirid from the get-go.

This unbelievable slugfest ended as dramatically and violently as it started. Bigdash had to muster all the courage he had after almost getting knocked out four times to land a hard knee followed by a right cross to Svirid's jaw.

We won't say anything more as we'll leave all the other details for you to enjoy.

#1. Aung La Nsang vs. Ken Hasegawa I - ONE Championship: Spirit of a Warrior

If you want to convert anybody into an instant ONE Championship fan, immediately show them this fight. 'The Burmese Python' Aung La Nsang, considered one of the greatest MMA champions ever, made his first ONE Championship middleweight title defense in his home country of Myanmar.

While the Burmese national hero was expected to steamroll the relatively unknown Hasegawa, no one saw how this epic match would turn out.

'War of attrition' might not even be enough to describe this unbelievable fight. The level of courage Aung La and Hasegawa displayed in this fight is, for the lack of a better term, inhuman.

Not a lot of fighters in the world can survive the amount of damage, exhaustion and hurt the two fighters put each other through. It makes you wonder if they effectively chipped away years from their lives just by going those five rounds.

Thunderous chants of 'Aung La!', seemingly coming from the entire nation of Myanmar, pushed the ONE Championship middleweight champion beyond his limits. The invading foreigner Hasegawa never backed down and fought just as valiantly as the hometown hero.

In the end, Aung La channeled all his remaining energy to his right fist and collided it straight on Hasegawa's jaw. It was too much for the brave Japanese warrior as he fell lifelessly to the floor, ending the bout via knockout.

The crowd erupted into a frenzy as their proudest son just won the greatest fight in ONE Championship history.
