It's the fight everybody wants to see.
Last year, Conor McGregor met Nate Diaz at UFC 196 and the American was victorious by submission with 48 seconds left in the second round.
Five months later at UFC 202, 'Notorious' won by decision in one of the fights of the year, but the question remains - who will be McGregor's next opponent?

According to The Sunday World via The Independent, the 29-year-old is very close to signing a deal to take on Nate Diaz on December 30.
The trilogy will apparently take place in Las Vegas, a perfect way to end a spectacular calendar of fighting.
Friends and family are so sure the fight will take place that they have already booked flights to Vegas, according to the report.

Following his defeat to Floyd Mayweather in the boxing ring, McGregor's manager Audie Attar told MMAjunkie that Diaz is wanted by McGregor:
"He wants that triology," Attar said, before confirming all the other options on the table.
"You've got Khabib calling him out, then you obviously have Tony Ferguson and Kevin Lee who are fighting for the interim lightweight title.
"You have Max Holloway, who is the 145 champ now, who Conor beat after blowing out his ACL at the beginning of the fight. You have options, and he loves mixed martial arts.

"Everyone is like, 'oh he's going to retire - he made so much money'. He's ambitious. He's super ambitious, and he loves to fight.
"He loves to compete and he's a superb professional athlete. So, there's much more Conor McGregor that everybody will see, and we'll see what's next."

The fighter lasted ten rounds before the fight was stopped - going longer than many other thought - and was equally humble during his post-fight press conference.
Who do you think will be victorious - McGregor or Diaz?
