Jones recently was given the green light to return to competition after negotiating the terms of his suspension from the U.S. Anti-Doping Agency (USADA). He settled at a 15-month suspension, though his maximum penalty could have been much longer. Providing USADA with cooperation in other potential cases reduced his penalty.

Gustafsson said he doesn’t believe Jones’ lengthy stints away from competition are going to be an issue come fight night, though.

“I don’t think it will affect him at all,” he said. “I’m preparing for the best Jon out there. I’m preparing for a better Jon this time than last time. I just want to fight the best. No excuses after this fight. It doesn’t matter what he’s been doing or what I’ve been doing. It doesn’t matter now. It’s all about the 29th.”

Their first meeting was arguably a closer fight than the scores – two 48-47s and a 49-46 – normally would indicate. In the aftermath, Jones said he didn’t train for the fight, and also said he was drinking to the point of blacking out a week before his fights back in those days.

But Gustafsson believes that’s all been just talk by Jones to protect himself, and perhaps an attempt to give Gustafsson some pause.

“It gives me a smile on my face, nothing else,” Gustafsson said. “I know he’s making up these things to create ghosts in my head or excuses for his performance. I have no clue. But it doesn’t really matter. I know this guy is the best guy out there because he’s training so hard. He’s dedicated, and he is the best guy out there. It’s impossible for him not to train and perform like that. He has to train.”

And a fully trained Jones is what Gustafsson said he wants for UFC 232. In his estimation, if he beats him, which he said he will do, that should reflect better on him than beating a Jones that isn’t prepared.

One way or another, the 31-year-old Swede believes a new era is about to happen at light heavyweight.

“At the end of the day, it all comes down to who wants it more,” Gustafsson said. “I’m just the guy for him. The Jon Era is over. The Jon Era is over – I’m here to take that over and I’m here to beat him, once and for all. … I just have to wake him up, and I will.”
