The animosity between Israel Adesanya and Marvin Vettori stands out as one of the most stubborn personal and professional clashes in modern mixed martial arts. Long before they settled scores inside the octagon for the undisputed middleweight championship, their friction grew from a casual backstage glance into a multi-year rivalry defined by conflicting personalities, contrasting styles, and an inability to let the past go.
At its core, the rivalry tells a story of elite martial artists chasing divisional dominance while carrying genuine personal distaste for one another. While many UFC feuds fade after a definitive judges' decision, this matchup lingered because neither competitor ever respected the other's path, skills, or claims to the belt. Understanding how this bad blood brewed requires looking past the promotional hype and examining the actual timeline, the tactical shifts, and the psychological battle that shaped their two memorable encounters.
The Origin of the Feud: A Brief Encounter in Vegas
Long before anyone penciled in a championship bout, the tension began with a fleeting, unspoken confrontation. In 2017, backstage at an event in Las Vegas, Adesanya and Vettori crossed paths. A simple look exchanged in a hallway sparked an immediate dislike. Adesanya recalled that Vettori offered a smug smirk, which planted the seed for a matchup that Adesanya actively pursued as soon as he entered the UFC.
Most fighters brush off minor backstage stares, but both men possessed the stubborn pride needed to hold onto a grudge. When matchmakers offered Adesanya multiple options for his sophomore UFC appearance, he bypassed easier paths to specifically request the Italian contender. Vettori, driven by a fierce desire to prove he belonged among the elite, welcomed the hostility. What started as accidental friction quickly evolved into a toxic dynamic that neither athlete tried to conceal from the public. Further details on this are explored by Associated Press.
Their First Meeting at UFC on FOX 29
In April 2018, the two middleweights clashed for the first time at UFC on FOX: Poirier vs. Gaethje. At the time, Adesanya was a rising prospect making waves with flashy kickboxing credentials, while Vettori was a durable, gritty grappler looking to gatecrash the rankings.
The fight itself was a closely contested affair that exposed early questions about Adesanya's takedown defense while highlighting Vettori's relentless forward pressure. Vettori managed to secure critical grappling exchanges, particularly in the final frame, making it a nervous wait for the scorecards. Ultimately, Adesanya walked away with a split decision win.
Instead of closing the book, the result poured fuel on the fire. Vettori firmly believed he did enough to win, arguing that control time and wrestling supremacy deserved the nod under the scoring criteria. Adesanya, meanwhile, viewed Vettori as a limited fighter who relied on stalling positions. The split verdict ensured that neither man found closure, setting the stage for a much larger collision down the line.
The Championship Stakes at UFC 263
As the years rolled on, both fighters climbed the ladder. Adesanya captured the middleweight championship and successfully defended it multiple times, cementing his status as a pound-for-pound striker. Vettori bounced back from their initial meeting with a strong win streak, defeating opponents like Kevin Holland and Jack Hermansson to position himself as the clear number-one contender.
By the time they rematched at UFC 263 in June 2021, the stakes had reached their peak. The build-up featured relentless trash talk, heated press conferences, and personal insults about their respective gyms and training partners. Vettori entered the cage wearing the mantle of a relentless challenger who promised to drag the champion into deep waters, while Adesanya aimed to deliver a definitive, zero-doubt performance that would silence his most vocal critic once and for all.
Tactical Breakdown: Striking Versus Grappling
The rematch at UFC 263 offered a fascinating study in contrast. Vettori's game plan relied heavily on closing the distance, avoiding Adesanya's range-finding kicks, and dragging the fight to the canvas. However, executing that plan against an elite counter-striker proved exceptionally difficult.
Adesanya showcased exceptional defensive footwork and distance management. Whenever Vettori shot for a takedown, Adesanya anticipated the level change, framing his hips and utilizing superior reaction speed to stuff the attempts. Vettori struggled with the sheer speed differential, often winging wide punches from the outside that missed their mark or landed harmlessly against Adesanya's guard.
- Distance Control: Adesanya punished Vettori's lead leg with low kicks, disrupting his forward momentum.
- Takedown Defense: Vettori attempted multiple takedowns but only found sustained success when he altered his entries, leading to frustrating stalramites against the cage fence.
- Clinch Work: Adesanya routinely neutralized Vettori's strength by using overhooks to turn him and escape dangerous positions.
When the final horn sounded, the judges rendered a clear unanimous decision (50-45 across the board) in favor of the champion. Vettori's durability kept him upright through five punishing rounds, but he failed to mount significant offensive damage or sustain top control.
Psychological Aftermath and Legacy
The aftermath of UFC 263 highlighted the stark difference in how both athletes processed defeat. Adesanya demonstrated an ability to move forward, viewing the chapter as closed history. Vettori, true to his stubborn persona, continued to voice grievances about the scoring and maintained that his grappling success warranted a closer look.
This rivalry matters in the broader context of MMA history because it highlights the friction between pure kickboxing artistry and relentless pressure-wrestling. While they never developed a mutual respect, their paths forced both men to evolve. Adesanya proved his grappling defense against a dedicated chain-wrestler, while Vettori solidified his reputation as one of the toughest, most durable athletes to ever compete at 185 pounds.
