We’re still a good three months away from the big UFC Fight Night event in Boston, headlined by a bantamweight title bout between champion TJ Dillashaw and former titlist Dominick Cruz.

There’s no time like now to begin the trash talk, though.

Former UFC lightweight champion Anthony Pettis, who will face another 155 lb contender in Eddie Alvarez at the show’s co-main event on Jan. 17 at the TD Garden, fired a few shots with MMA Junkie yesterday.

“I’m focused on Eddie Alvarez, another good fighter, (but) based on his last two performances, I’m not that impressed,” Pettis said. “If I’m in there 100 percent and I’m healthy and fight the way I fight, I don’t think he’s even a challenge.”

By the time the bell rings for the Alvarez bout, Pettis will have been out of the Octagon for almost a year. The man they call “Showtime” last fought in March, losing a unanimous decision (and his UFC lightweight title) to Rafael Dos Anjos. But Pettis says the layoff may work to his advantage against Alvarez.

“I’m going to go back to focusing on what I’m good at; last fight I was trying to focus on watching the wrestling and all that stuff,” Pettis said. “When I’m out there focusing on what I’m going to do and not what they’re going to do, I feel like I have the best results. Obviously we’re going to watch a little bit of film and how he stands, but other than that, it’s just me being myself.”
