Flyweight champion Demetrious Johnson currently occupies the top spot
Dana White has said that Conor McGregor should be recognised as the number one pound-for-pound fighter in the UFC rankings.
The rankings are decided by the media and White hit out after the Irishman was not placed atop the list after unifying the featherweight and lightweight titles at Madison Square Garden in November.
Speaking on the Michale Kay show White said: "When you talk about the pound-for-pound, they don't have Conor McGregor as the pound-for-pound - the media does the ratings - when you talk about what pound-for-pound really means, how is it not Conor McGregor?
"The guy was the 145 pound champion, 155 pound champion, and beat a guy at 170. That's what pound-for-pound really means," he added.
Current flyweight champion Demetrious "Mighty Mouse" Johnson occupies the top spot. He is currently on an 11 fight win streak in his division. His last loss came at bantamweight against Dominick Cruz in 2011.
McGregor has endured a memorable 12 months. He knocked out Jose Aldo in 13 seconds to become the UFC's featherweight champion last December.
He was due to face lightweight champion Rafael Dos Anjos in a champion-versus-champion super fight at UFC 196 last March but Dos Anjos pulled out due to injury. In a bid to save the PPV event, McGregor agreed to fight Nate Diaz on short notice at the welterweight limit of 170 lbs.
McGregor dominated the opening round but his cardio dipped in the second and Diaz submitted the Irishman.

McGregor and Diaz rematched at UFC 202, again at welterweight, where McGregor won a deserved majority decision in an entertaining five round slug-fest.
The Irishman finally got his chance at history when he agreed to a bout with new lightweight champion Eddie Alvarez at the promotion's epic UFC 205 event at Madison Square Garden in New York.
McGregor dominated the fight knocking Alvarez down three times in the first round before referee John McCarthy called a halt to the bout mid-way through the second.

The Irishman became the first fighter in UFC history to hold two divisional titles simultaneously and now sits in the number two spot on the UFC's pound-for-pound rankings.
