Undefeated junior middleweight contender Tim Tszyu is training away for next month's mandatory fight with WBO, IBF, WBA, WBC world champion Jermell Charlo.

Their fight takes place on January 28th at the Mandalay Bay in Las Vegas.

Tszyu has already traveled over to the United States and is currently training hard in Los Angeles, California.

The unbeaten Aussie is not worried about any potential intimidation tactics from Charlo.

“And good, let all those antics come in,” Tszyu told Fox Sports.

“There’s nothing to lose for me. I’ve got no pressure. The pressure’s on him. He’s the one putting pressure on himself … saying he’s going to knock me out in a couple of rounds. I know that’s not going to happen … watch what it does.”

In the aftermath, Tszyu doubts there will be any type of friendship with Charlo.

“I’m not going to be calling him saying ‘let’s go for a coffee.’ We’re two completely different personalities, we’re not mates. We will probably never be mates, but I do have a certain respect for him as a fighter," Tszyu said.

Now that he's training in the United States, Tszyu is being tested by tough sparring partners.

Tszyu is embracing the newfound scenario of playing out the most important camp of his career in a new training setting.

“And it’s not just the physical preparation,” Tszyu said. “This is the jungle, man. I feel like I’m in the jungle. It’s just you by yourself — a different feeling. There is just something about this place, America. This is why I came over here so early; got my team, got everything … (laughs) left all females at home, everyone is back home. So now it’s all like this - tunnel vision. I’m a monster, that’s it.”
