UFC lightweight champion Rafael dos Anjos has said that he would "crush" Conor McGregor if the Irishman decided to come after his title.
In September, McGregor said that he would consider moving up to the lightweight division should he dethrone Jose Aldo as featherweight champion at UFC 194 in December.
However, Dos Anjos, who beat Anthony Pettis to become the lightweight champion at UFC 185 in March, believes that McGregor wouldn't stand a chance against him in the Octagon.
"I don't care about (Conor) McGregor. He's a small guy, I would crush him," Dos Anjos told FOX Sports. "If he wants to take my title I would love to crush him, but right now I don't think he's a big challenge. There are bigger names to beat."
Dos Anjos, who will defend his title against Donald Cerrone at UFC on FOX 17 on December 18, added that McGregor should not be acting like a champion just because he was crowned the interim UFC featherweight champion after beating Chad Mendes at UFC 189 in July.
McGregor was supposed to face Aldo for the featherweight title at the event, but Aldo pulled out after suffering a rib injury while training.
"I have honor on my belt. Not a fake belt," Dos Anjos said. "I have a real belt because I fought against the best. That's why I think for me it's most important. Right now my focus is on this Cerrone fight, but then I want Khabib Nurmagomedov because I want to clean that loss off my record."
While McGregor is fast becoming the UFC's most prized asset, Dos Anjos revealed that he is more interested in facing and beating the best fighters in his division.
"More important is to fight against the best. You do it the hard way, you can't do it the easy way. That's what's most important for me," Dos Anjos said. "I go back home, before I go to sleep, I put my head on my pillow, I know I fought against the best, that's the most important thing to me."
