1. Anthony Pettis

'Showtime' came into the UFC as WEC Champion, famous for his 'Ninja kick' when beating Benson Henderson in 2010.

He was welcomed by Clay Guida in his first UFC bout, where he got a rude awakening. Since then, he has looked unstoppable finishing Joe Lauzon, Donald Cerrone and then beating Benson Henderson for the second time in his career to win the UFC title.

He'll face former Strikeforce Lightweight Champion Josh Thompson in December.

2. Benson Henderson

Henderson's dominance as UFC Lightweight champion came to an end as he submitted to Pettis in his last bout.

However, before that he triumphed through the division, beating Frankie Edgar twice, walking through Nate Diaz and earning a win over Strikeforce 155lbs champion Gilbert Melendez.

With the second defeat of this career to 'Showtime' it's difficult to know what'll be next for The MMA Lab stand out. He's talked about a possible move to welterweight.

3. Gilbert Melendez

Maybe Melendez should be UFC champion.

His razor thin decision loss to Henderson could have went either way. He bounced back from the loss beating Diego Sanchez in one of the best fights of 2013.

Another win in early 2014 should see 'El Nino' earn himself another shot at the title.

4. TJ Grant

Who would have thought that when Grant dropped to 155lbs he would become a title contender.

He's gone 5-0 since dropping weights, and has looked an absolute beast. Grant was in line to meet Benson Henderson before suffering an injury.

His last win came against number one contender Gray Maynard, where he won via KO.

A number one contenders match with the fighter above seems the fight that makes most sense.

5. Eddie Alvarez

Alvarez is the best lightweight outside of the UFC. He lost his Bellator title against Michael Chandler in 2011, and avenged his defeat last week in a split decision win.

Beating the likes of Shinya Aoki and Pat Curran, his win pushes him one step closer to his dream - to fight in the UFC.

6. Josh Thompson

At 35 years old, Thompson looks to be improving with age. He lost a tight split decision loss in Strikeforce to Gilbert Melendez then produced his career best performance against Melendez's team-mate Nate Diaz last time out, landing a devastating head kick.

That earned him a title shot against Anthony Pettis in December

7. Michael Chandler

Despite his loss to Alvarez, Chandler is still a top top fighter.

He could have very easily got the nod in his last fight, however, suffered his first career defeat.

The Alliance MMA fighter will be back with a bang. 

8. Nate Diaz

Diaz dropped back to 155lbs and tore through the division.

He submitted both Takanori Gomi and Jim Miller as well as completely out-striking Donald Cerrone.

The Caesar Gracie fighter now has back to back losses - to Benson Henderson for the title and he was KOd by Josh Thompson.

He fights Gray Maynard for the third time at then end of the month.

9. Rafael Dos Anjos

Dos Anjos is very much the dark horse of the division.

He looks looked super impressive lately, with much improved striking and wrestling.

His latest victory over Donald Cerrone was by far the best of his career and he is one to watch in the division

10.  Gray Maynard

Almost a UFC 155lbs champion after his two thrilling title fights against Frankie Edgar.

He lost last time out against TJ Grant and will meet Nick Diaz next.
