He’s a few months removed from his biggest career win, and he’s got a high-profile opponent next month at UFC on FOX 13 — so one might expect Rafael dos Anjos to be sounding satisfied with the direction of his career.

The Brazilian enjoyed a TKO victory in his first-ever appearance in a UFC main event back in August — a devastating first-round stoppage of former UFC Lightweight Champion Benson Henderson.

But dos Anjos, who has now won six of his last seven bouts, raising his MMA record to 22-7, evinced some frustration with the UFC.

Dos Anjos, now ranked the #3 lightweight in the UFC’s official ranking, will battle Nate Diaz on the undercard of UFC on FOX 13, which is headlined by UFC Lightweight Champion Anthony Pettis’ title defense against Gilbert Melendez.

Diaz, dos Anjos says, didn’t really deserve the fight he’s getting. For that matter, says dos Anjos, nor does Melendez deserve a title shot.

“I think he doesn’t deserve it,” dos Anjos remarked regarding Diaz to The MMA Hour with Ariel Helwani. “I accepted this fight because I want to be active, and I want to fight at the same time as a title fight — a good time to fight next. I want to have my chance; I want to be the first Brazilian to get this belt.”

Melendez, dos Anjos notes, has fought only three times in the UFC.

“His first fight was the title and he lost,” dos Anjos says. “He almost lost to Diego Sanchez; it was a tough fight — and he’s fighting for the title again? In my opinion, it’s not fair. After I beat Nate Diaz, I think I deserve a title shot.”
