With the success of the addition of both featherweight and bantamweight divisions, the UFC has acted quickly to capitalize on this sensation with a new weight class: flyweight. This will see 125-pounders pitting their skills against one another.
This expansion throws up many interesting dynamics. What fighters do the UFC import, and which fighters will move down from bantamweight. Many believe that the UFC's smaller fighters at bantamweight, such as Joseph Benavidez, Scott Jorgenson and Demetrious Johnson, will flourish in this new weight division.
Here, I will introduce some of the world's greatest fighters at 125lbs, who Dana White should look to sign.
Honorable mentions that didn't make the grade include Yuki Shojo, Ulysses Gomez, John Dodson and former Olympic bronze-medallist wrestler Alexis Vila.

Jussier da Silva, often known as his nickname "Formiga", is a former top-ranked flyweight star and current Shooto South American champion.
Boasting an impressive ground game typical of his Brazilian nationality, Formiga was on an undefeated winning streak of nine, until that was snapped in an upset to Ian McCall.
Formiga will be looking to restart his habit of winning with a fight against Mamoru Yamaguchi at the USA's premier flyweight promotion Tachi Palace Fights.
Ian McCall, otherwise known as his unusual moniker "Uncle Creepy", is the American flyweight that stopped Jussier da Silva's dominance of the 125lbs weight class.
McCall was a heavy underdog for that fight, but he does boast an impressive resume of wins and experience. Back in 2009, McCall fought UFC bantamweight title-holder Dominick Cruz to an unanimous decision loss at WEC 38.
After defeating the much-vaunted da Silva, McCall has been rewarded with a Tachi Palace Fights title shot against Darrell Montague later this year.
Mamoru Yamaguchi is man who is loved for his fights almost as much as his hairstyle.
The afro-sporting Japanese fighter, who hasn't lost a fight since being submitted to Shinichi Kojima in 2008, is a stalwart of the 125lbs flyweight class.
Yamaguchi has 10 career knockouts to his name, without being the victim of a KO himself. He has stopped his three last opponents via TKO or KO.
Yamaguchi recently started to fight more state side to boost his profile, and is due to fight Brazilian Jussier da Silva next in the Tachi Palace Fights' cage.
Darrell Montague is currently America's cream of the crop at flyweight, as the champion of the USA's deepest flyweight talent pool at Tachi Palace Fights.
At the young age of 23, this prospect is the most exciting fighter around at flyweight, attributed with an array of attacks. He boasts a record that consists of many knockouts of differing types, such as spinning back fists, punches and kicks.
"The Mongoose" dominated Ulysses Gomez to a decision to win his crown and has the first defence of his title against up-and-comer Ian McCall later in August.
Yasuhiro Urushitani is a veteran in the Japanese lighter weight fight circuit, but has shown time and time again that he still has what it takes at the top of the flyweight ranks.
Urushitani possesses some of the best wrestling in the division, and loves to smother his opponents and control the fight the way he wants it.
The Japanese fighter, the current Shooto flyweight champion hasn't lost since 2008, and gets the chance to avenge his defeat against Yuki Shojo later this year.
When there is talk about the UFC branching out to Japan in the near future, the American promotion should look at Urushitani as a possible star signing.
