Fan favourite Charles Oliveira tops the bill behind enemy lines as he looks to reclaim the lightweight title he lost on the scales last time out in front of a hostile crowd when he takes on imperious contender Islam Makhachev.

Oliveira is currently on an incredible 11-fight win streak including a trio of finishes against Michael Chandler, Dustin Poirier and Justin Gaethje in his past three bouts while Makhachev carries an impressive 11-1 record in the UFC into his first ever world title bout.

It's the first time ever that two fighters on double-digit win streaks will have met inside the Octagon and it's one you simply cannot miss!

They'll be supported by a cracking co-main event when bantamweight king Aljamain Sterling takes on former champion TJ Dillashaw in the second defence of his 135lb crown.

The 'Funk Master' proved his legitimacy as a champion with a convincing win over Petr Yan last time out and will be out to take another impressive scalp in the form of the two-time champ Dillashaw.

They'll be supporting by another wicked 135lb contest when Sean O'Malley leaps up the rankings to face number one contender Petr Yan in a fight Dana White has suggested could even produce the next challenger to the bantamweight crown.

But that's not all - with unmissable contests packed in top to bottom all the way throughout a bumper card at UFC 280, you don't want to miss out on this must-see event in Abu Dhabi.

UFC 280: What's the story?

It's being billed as the biggest and best fight card of the year so far in Abu Dhabi with a slate of stunning scraps to look forward to from the Etihad Arena.

The former champion, Charles Oliveira, tops the bill in a cracking contest against surging lightweight force Islam Makhachev for the vacant 155lb belt.

Oliveira was controversially deposed as the champion prior to his last outing when he failed to make the lightweight championship weight limit - a mistake he put down to a pair of faulty scales at the UFC 274 weigh-ins in Arizona back in May.

He went on to beat Justin Gaethje regardless but shorn of the strap around his waist, the Brazilian now must reclaim what was once his in a terrific showdown against the other in-form phenom of the division.

Much has been made of Makhachev being the apparent reincarnation of the recently-retired Khabib Nurmagomedov - but the Dagestani fighter has yet to test himself at the highest level to truly be considered worthy of that status.

Despite that, his 10-fight win streak makes him the second most prolific man in the lightweight division, behind only Oliveira for active wins at 155lb.

The fight will see two men on 10+ win streaks go head-to-head for the first time in UFC history and it's hard to see how it will be anything other than an absolute classic when the Octagon door closes on Saturday night.

They will be preceded by Aljamain Sterling's second championship defence in the other world title fight going down this Saturday night as the New Yorker takes on TJ Dillashaw for the 135lb strap.

Sterling blew away any lingering questions over his credibility as the king of the bantamweights with an impressive victory over Petr Yan last time out to retain UFC gold.

And the 33-year-old could further underline his status as the best of the best with a win over one of the greatest bantamweights of all time, the two-time champion Dillashaw, on Saturday night.

Dillashaw, meanwhile, is out for redemption having recently returned from a two-year suspension for using performance enhancing drugs that has left his reputation in tatters and threatened to ruin the legacy of one of the UFC's most talented performers.

Now 36, and in the midst of a shark tank of dangerous rivals, the former Division I college wrestling standout is out to prove he still belongs among the elite with a statement victory over the incumbent king.

Petr Yan vs Sean O'Malley is another fight on the main card which has captured the imagination over recent weeks and months with the former interim and undisputed champ Yan taking one one of the hottest prospects in the UFC.

Despite nine fights in the promotion so far, O'Malley remains something of an enigma in terms of how good he really can be in the UFC; taking on the number one contender in the division will determine a lot about his future aspirations for the belt.

Meanwhile Yan believes a win over the popular O'Malley will tee him up perfectly for an immediate return to world title contention with eyes firmly fixed on the winner of Sterling vs Dillashaw in the co-main event.

Two of the most dangerous lightweights on the planet clash in another belter this Saturday night too when Beneil Dariush throws down against Mateusz Gamrot.

Dariush had been pipped as a potential title challenger for the latter half of this year until an ill-timed leg injury curtailed his progress and seemingly moved him back down the queue of contenders.

Gamrot is the man taked with welcoming him back into the Octagon with the Polish fighter looking to build on a thrilling, hard-fought win against Armen Tsarukyan last time out.

Plus there's a wicked women's flyweight contest kicking off the main card as the number one contender Katlyn Chookagian takes on Manon Fiorot in a fight that could crown the next title challenger at 125lb.

It's going to be one of the books tonight - so don't miss it!
