The UFC matchmakers have some important decisions to make after Saturday's UFC 299 card in Miami.

The stacked event was headlined by a bantamweight title fight, with champion Sean O'Malley taking on challenger Marlon "Chito" Vera—the man behind the only loss of his career to date. The second time around, O'Malley evened the score with a wide decision win, cementing himself as the true king of the bantamweights in the process.

In the co-headliner, lightweight legend Dustin Poirier rebounded from a tough knockout loss to Justin Gaethje with a thrilling knockout win over streaking French contender Benoit Saint-Denis.

That was preceded by a pair of welterweight fights, with former Bellator star Michael "Venom" Page defeating Kevin Holland in his UFC debut, and streaking Australian contender Jack Della Maddalena knocking out Gilbert Burns for the biggest victory of his career to date.

Like the main event, the main card opener also occurred at bantamweight, where former champ Petr Yan picked up a hard-fought decision win over Song Yadong.

All of the UFC 299 main card winners can look forward to huge fights next time out, but it remains to be seen what exactly the UFC matchmakers have planned.

Here are five fights we hope they'll consider when the dust has settled.

Sean O'Malley vs. Merab Dvalishvili

After his impressive decision win over "Chito" in the UFC 299 main event, Sean O'Malley called for the chance to become a two-division champion by taking on new featherweight king Ilia Topuria. It was a bold callout, and an O'Malley vs. Topuria fight would be big business for the UFC, but let's just hold our horses. O'Malley still has a lot of work to do at bantamweight, namely defending his belt against Georgia's Merab Dvalishvili.

With 10-straight wins in the rear-view mirror, Dvalishvili inarguably deserved a crack at the bantamweight belt before Chito, but was deprived of the opportunity due to the Ecuadorian's history with O'Malley.

Now that Chito and the champ have settled their score, it's time for Dvalishvili to get his shot. He deserved it after beating Jose Aldo and Petr Yan, and after his recent decision win over former two-division champion Henry Cejudo, he's simply undeniable.

If O'Malley gets by him, then we can revisit the potential Topuria super fight, but for now, this is the only fight to make for the bantamweight champ.

Dustin Poirier vs. Alexander Volkanovski

After a brutal knockout loss to Justin Gaethje, Dustin Poirier was in desperate need of a win in his UFC 299 fight with the rising Benoit Saint-Denis. He got the win he needed in emphatic fashion, shutting the lights out on the Frenchman in a wild, Fight of the Night-winning brawl.

Poirier has options after his big win in Miami. If the next crack at the champ Islam Makhachev goes to Gaethje, as widely expected, the winner of next month's Charles Oliveira vs. Arman Tsarukyan would be a great option.

However, we're going to suggest an option that's a bit outside the box: former featherweight champ Alexander Volkanovski.

Volkanovski is considered one of the best fighters of all time, but last month, saw his title reign come to a crashing halt at the hands of Ilia Topuria. Since then, he's been adamant that he only wants a rematch with the new champ—an opportunity he probably deserves—but at this point, it would be great to see the Australian legend focus on legacy fights. Some of the best of those fights exist at lightweight, where Volkanovski has competed before.

Poirier seems like a great option. Both guys rank among the best fighters of this generation, and both are in need of a big challenge to get keep them invigorated. If this fight were to be made, the winner would also be right in the lightweight title conversation, so there's plenty of reason for both men to take it.

One way or the other, it's clear that "The Diamond" is still shining at 155 pounds.

Michael Page vs. Stephen Thompson

Michael "Venom" Page is one of the best fighters in Bellator history, and on the UFC 299 main card, he made a successful UFC debut with a decision win over Kevin Holland.

After the win, there is already talk of a potential all-England showdown between Page and reigning welterweight champ Leon Edwards, but Page is still behind Belal Muhammad and Shavkat Rakhmonov in the race for a title shot at the moment, so let's put a pin in that idea, and match the Brit up with two-time title challenger Stephen "Wonderboy" Thompson.

A potential Page vs. Thompson fight is one of the most alluring striking clashes the UFC can make right now. Both guys are karate specialists with unusual styles that confound the majority of their opponents, and both are capable of violent knockouts when they're at their best.

The fight certainly makes sense for Page, and for it's definitely an opportunity Wonderboy would leap at as he looks to rebound from a submission loss to Rakhmonov in his last fight.

If Page passes this test, a fight with Edwards—whether there's a title on the line or not—could be the one to make.

Jack Della Maddalena vs. Ian Machado Garry

Jack Della Maddalena has long been considered one of the hottest new contenders in the crowded welterweight division, but after split decision wins over Bassil Hafez and Kevin Holland in his past two fights, he lost a bit of his hype. His UFC 299 knockout win over Burns, one of the best welterweights of this generation, completely revived his hype, and gave him a huge push toward title contention.

While a title shot is probably not far off for the Australian, he's still got some work to do before he gets there. In the meantime, a fight with unbeaten Irishman Ian Machado Garry seems like just the ticket.

Garry, like Della Maddalena, is one of the brightest new contenders in the division, and after a decision win over Geoff Neal, is closing in on a title shot himself. Much like the Australian, however, he is still a win or two shy of the opportunity.

Match these two strikers up on a pay-per-view main card, and trust that somebody will hit the deck, while the other asserts themselves as a legitimate threat to the champion.

Petr Yan vs. Marlon Vera

After three straight losses, former bantamweight champion Petr Yan finally got back to winning ways at UFC 299, defeating Chinese contender Song Yadong by unanimous decision.

The win over Song won't be enough to earn the Russian a title shot—certainly not before his recent foil Merab Dvalishvili—but another win or two could set him up for the opportunity to reclaim the belt.

Our pick for his next opponent is none other than Marlon "Chito" Vera, who came up short against the champion Sean O'Malley in the UFC 299 main event.

Chito had little to offer O'Malley in Miami—outside of a fifth-round body shot that caused the champ to double over—but remains one of the bantamweight division's top dogs.

He and Yan also happen to be ranked right near each other in the top 15, and Nos. 5 and 4 respectively, and as vicious strikers, they match up very well on paper.

This one could easily headline a Fight Night card, or bolster a future pay-per-view. One way or the other, it's a great fight that would tell us a lot about where the two men belong in the weight class.
