5 most intense and personal rivalries in ONE Championship history

#2. The brewing rivalry between ONE Championship bantamweight king Bibiano Fernandes and John Lineker

ONE Championship's most dominant champion Bibiano 'The Flash' Fernandes has always been the cool-headed type of fighter. It wasn't until he met John 'Hands of Stone' Lineker that the Brazilian showed his angrier side.

Lineker is now set to face Fernandes for his ONE Championship bantamweight strap, with the intensity reaching a fever pitch.

The rivalry may be in its infancy at the moment, but the level of animosity between the two merits them to be on this list. It has the makings of a true MMA rivalry that can produce great moments in and out of the cage.

The champion came out shooting verbal attacks at Lineker while the challenger didn't back down. The ONE Championship king recently spoke to the South China Morning Post about his opponent:

"F*ck John Lineker. If you want to fight me, you want to get the belt, come, let’s do this but in a good way. That’s the way we do it, like if we fight in the street, no problem."

Just like that, the MMA world is now at the edge of its seat waiting for these two to finally clash. The bad blood is real and this might be the first true grudge match in ONE Championship history.

#1. Bibiano Fernandes and Kevin Belingon produce the greatest rivalry in ONE championship history

Bibiano 'The Flash' Fernandes' dominance over his weight class is spotless except for his wars against Kevin 'The Silencer' Belingon.

The Filipino striker was the only one to solve the Brazilian jiu-jitsu wizard's grappling puzzle and nullify his game. Together, the two had a rivalry for the ages as they faced each other an unprecedented four times.

The first two bouts were split 1-1 with the third dance ending in controversy. In the rubber match, Bibiano won via disqualification as his Filipino foe accidentally hit him with elbows in the back of the head. Though the foul was indeed accidental, the ending stirred some bad blood between the two.

In their fourth fight, Fernandes put a definitive end to their rivalry. Belingon was aggressive as always, but Bibiano adjusted his MMA game and successfully melded his striking with his grappling.

The Brazilian choked his opponent out in the second round, closing out the greatest rivalry in ONE Championship history.
