New UFC featherweight champion Conor McGregor is also eyeing the Lightweight title.

McGregor, 27, has been all the buzz after he dismantled Jose Aldo within 13 seconds in the first round of their bout. After taking the featherweight crown from Aldo, McGregor looks to move up to the lightweight division, seeking to become only the third fighter to have two titles in two different classes.

Rafael dos Anjos and Nate Diaz both called out the Irishman at UFC Orlando on Saturday.

Diaz, in an interview with Joe Rogan after winning over Michael Johnson, went on an expletive filled rant calling out McGregor.

"Conor McGregor, you're taking everything I work for, motherf------r. I'm gonna fight your f------g ass. You know what the real fight-the real money fight-is: Me," Diaz said. "Not these clowns that you already punked at the press conference. Don't no one want to see that. You know you beat them already. That's an easy fight. You want that real s--t? Right here."

Dos Anjos, who defended his title Donald Cerrone in the first round, also took shots at McGregor.

Listen, McGregor, if you want to come to the lightweight division, this is my division," said the Lightweight champion, per ESPN's Brett Okamoto.

Conor McGregor has responded to the challenges on his Twitter, saying "I want them to beg me."

Bleacher Report's Matt Jones explains the pros and cons of McGregor's move to the Lightweight class.

Given the power he's long showcased at featherweight, seeing how hard McGregor could hit at lightweight is a tantalising proposition," Jones wrote. "It seems a more natural weight for the Irishman too, who has regularly looked gaunt at weigh-ins, with the cut taking a noticeable toll on his physique a day before the fight."
