Featherweight champion Jose Aldo (21-1) was able to retain his title after knocking out previously undefeated Chad Mendes (11-1). 

Aldo has now won 14 straight fights with 13 knockouts overall in his career. 

It's no secret that Aldo is the best featherweight in MMA today. But where does he rank all-time among featherweights?

5. Norifumi "Kid" Yamamoto

Record: 18-5 (1 knockout)

Biggest Accomplishments: One of the quickest knockouts in MMA history (4 seconds), K1 Hero's 2005 Middleweight Grand Prix Tournament winner

Although Kid Yamamoto has been just 1-4 in his last five bouts, in his prime he went 17-1.

Yamamoto was known for his aggressive fighting style which has earned him 13 victories by knockout. 

4. Hatsu Hioki

Record: 25-4-2

Biggest Accomplishment: Former Sengoku featherweight champion

Hatsu Hioki is one of the best grapplers to ever come out of Japan.

He holds notable victories over Mark Hominick, Jeff Curren and recently won his UFC debut over George Roop.

Hioki's four losses have all come by close decisions.

If Hioki can win his next bout at UFC 144, he could be the next man to challenge Jose Aldo.  

3. Alexandre Nogueira

Record: 13-6-2

Biggest Accomplishments: Held the Shooto Lightweight (143lbs) championship for over 6 years. 

Before a knee injury forced Alexandre Nogueira to vacate his Shooto championship, he was the longest reigning and defending champion in MMA history. 

Nogueira still holds the record for longest title at six years, eight months, and two days. 

Nogueira was a submission expert and one of the first successful featherweights in the sport. 

Although he's been 1-4 in his last five fights, Nogueira was one of the pioneers of the division and should not be forgotten. 

2. Urijah Faber

Record: 26-5

Biggest Accomplishment: Former WEC featherweight champion

Before moving down to bantamweight, Urijah Faber was one of the best featherweights in the world. 

Faber became the face of the WEC as he won the featherweight title and defended it a record five times. 

His wins at featherweight include Jens Pulver, Jeff Curran and Dominick Cruz. 

1. Jose Aldo

Record: 21-1

Biggest Accomplishment: Final WEC featherweight champion, first and current UFC featherweight champion

Jose Aldo is without a doubt the best featherweight in MMA history. 

On his current run, Aldo has defeated great fighters like Urijah Faber, Kenny Florian and most recently Chad Mendes. 

Aldo is one of the best strikers in MMA today and has an underrated wrestling and ground game. 

Perhaps the biggest thing on Aldo's side is the fact that he has accomplished so much at just age 25.
