The women's bantamweight division could probably join in the chorus of "how do you solve a problem like Rousey"?

She's like a Rubik's cube that punches back and the exact problem for UFC management at the moment is who to feed to their biggest star.

In short, while it's not a terrible problem to have – she's no Jon Jones - the UFC are short on options following Rousey's 34-second starching of challenger Correia on Sunday, a fight that not only showed off Rousey's rapidly improving striking skills, but also demonstrated the gap between good, very good and Rousey.

Correia is a solid, if not spectacular, competitor who looks at home in a brawl and the general consensus was that Rousey would not engage in stand up, but rather look for a clinch and go to work on the ground.

The general consensus was proved very, very wrong.

Rousey charged out at Correia and began swinging, backing the Brazilian into the fence.

Correia was trying to fight back but a crisp combo, followed by a knee, had her staggering away from the champion.

A laser-like straight right landed behind Correia's ears and switched her lights out, leaving the tough-talking challenger planted on her face, forcing referee Herb Dean to call the fight for Rousey via knockout.

The problem this has created for the UFC is to find a credible challenger.

Rousey's next dance partner will be Miesha Tate, a fighter she has already beaten twice.

While Tate has improved, Rousey has as well and there's no reason to think the fight won't end the same.

Cat Zingano, Alexis Davis, Sarah McMann and Correia have all been dealt with in under five minutes and the six and seventh-ranked fighters, Jessica Eye and Sarah Kaufman, are both coming off defeats.

Apart from the upcoming fight with Tate, which is still a chance to happen at Melbourne's UFC 193 in November, there are simply no credible contenders.

This leaves UFC president Dana White one option, until the next challenger is ready – give Rousey a fight with Brazilian knockout artist Cris Cyborg and put her 14-1-1 record to the test.

The problem is Cyborg, who is fighting at 140 pounds in her next fight, has said she cannot physically cut down to 135 pounds to fight Rousey.

Rousey, on the other hand, is the champion, and would gain nothing out of a catchweight fight.

It is, however, a fight that could sell a pay-per-view like no other women's bantamweight fight.

In other results, Perth UFC heavyweight Soa Palelei's charge towards a top-10 ranking was stopped in its tracks by a brutal uppercut from Antonio "Bigfoot" Silva, leaving Palelei with a 2-1 record from his past three fights.

From the start the West Australian looked tentative on the feet, but halfway through the first round he landed a judo flip on Bigfoot, putting the Brazilian on his back.

Palelei improved position and began reigning down shots before the bell went for the end of the first, and in a sign of things to come Palelei went back to his corner exhausted.

Despite being one round up on all three judges' scorecards, Palelei failed to fire a shot in the second as Bigfoot sensed blood in the water and moved in for the kill, with a massive uppercut dropping Palelei and forcing him to cover up.

He was bitterly disappointed in his performance after the fight and offered little in the way of comment, while Bigfoot, after two-straight knockout losses, was delighted to get back into the winner's column.

Shogun Rua improved his standing in the light-heavyweight division in the co-main event, withstanding an early barrage from Antonio Rogerio Nogueria to take a clear decision.

Rua is clearly not the fighter he once was, but he used effective kicks to keep Nogueira on the outside to claim a second win over Lil' Nog.

The biggest of the brothers, Antonio "Minotauro" Rodrigo Nogueria, may have ended his legendary career with a unanimous points decision loss to seven-foot tall Dutch kick boxer Stefan Struve.

Minotauro, a former UFC interim and Pride heavyweight grand prix winner, was a true innovator, perhaps the first true heavyweight to have a dangerous Jiu Jitsu game from his back and at 39 years old, after wars with countless other legends, now would be the right time to call it a day.
