UFC fans are eagerly awaiting to see who Conor McGregor will face next in the promotion now he has finally got his boxing match with Floyd Mayweather done and out of the way.The Notorious one could face one of two opponents, either Tony Ferguson or Nate Diaz.Tony Ferguson earned his right to fight McGregor after he defeated Kevin Lee via a triangle choke submission in the third round of their contest earlier this month at UFC 216 to become the interim UFC Lightweight Champion. A unification fight is therefore needed between Ferguson and McGregor to truly decide who is the UFC Lightweight Champion.Nate Diaz has his right to fight the Irishman as many UFC fans have been demanding a third fight between the two in order to make their feud a trilogy. Diaz won the first fight between the two at UFC 196, but Conor won the second contest at UFC 202, meaning a third deciding fight is needed to bring an end to this feud.On a recent episode of The Joe Rogan experience, via MMAFighting, Joe Rogan commented on who he thinks McGregor's next opponent inside the Octagon will be. The UFC commentator believes Ferguson has the edge as McGregor vs Tony Ferguson is the ‘logical fight’.Rogan said: “Conor made that post to Tony. He made an Instagram post. Grand Theft Auto with him holding a gun, driving a boat. Conor’s smart. He realizes that Tony’s an unusual, eccentric character. Conor’s an unusual, eccentric character, Tony’s an unusual, eccentric character too and Tony has the longest win streak in the UFC’s 155-pound division. He’s the interim champion and he’s the logical fight.”

However, he did make the case for a third McGregor vs Diaz fight to happen, as he believes if it doesn't happen, it would essentially mean leaving money on the table.

“The whole world doesn’t know Tony but the MMA world knows Tony, for sure. But the regular people are the people you really need to get a hold of to buy pay-per-views. [Nate] is the money [fight]... [But] Nate made four million bucks over two fights and he don’t give a f**k. He’s like, ‘Pay Me.’

"He beat Conor and in the second fight he arguably had a draw with Conor. He lost a decision based on a couple people’s opinion. Public opinion means a lot and if you went online and asked people who you think won that fight, I bet you would get very close to 50/50 Nate versus Conor.”

“The big money would be the Nate Diaz fight even if Nate beat him in the second fight,” continued Rogan. “You think you can go to the gas station right now and go, ‘Hey man, who’s Tony Ferguson?’ If you go to the average person and ask them who Nate Diaz is, way more people are gonna know who he is than Tony.”

Whichever fight happens, UFC fans will just be glad to see McGregor back inside the Octagon, as fans haven't seen him fight in MMA since he defeated Eddie Alvarez to become the UFC Lightweight Champion in the main event of UFC 205 at Madison Square Garden in November last year.
