The Northern Irishman makes a second defence of his WBA world title against Venezuela's Yonfrez Parejo on the undercard of the world heavyweight title unification fight between Anthony Joshua and Joseph Parker.

Burnett should have also been defending the IBF belt at Cardiff's Principality Stadium, but had to give up the title after just one defence due to conflicting demands for mandatory defences.

But Burnett (18-0, 9 KOs), 25, seems unconcerned about losing a belt due to boxing politics after beating Zhanat Zhakiyanov by unanimous decision in a title unification fight Oct. 21.

Burnett has enjoyed training alongside fellow Belfast boxer Michael Conlan and England's Josh Kelly, who is also in action on Saturday.

"I know Michael Conlan from the amateur days and there's a great energy in the gym at the moment with Michael, Josh Kelly, Charlie Edwards," Burnett told ESPN. "It's really good to have so many talented boxers in the same gym.

"We went over to train in Monaco just to break things up a bit but have done everything that we usually do for this fight. I've never been in front of a massive crowd before like this, but it won't faze me. I'm more focused on the fight than my surroundings.

"I don't pay too much attention to giving up the belt. Adam [Booth] explained it to me, why I had to give it up, and I've just kept my head focused on my opponent."

Burnett admits he knows little about Parejo (21-2-1, 10 KOs), who lost a split decision to Zhakiyanov in November 2015.

"I don't know too much about the opponent, but he seems to be a very clean boxer," Burnett told ESPN. Adam knows exactly what I have to do so we are working on a game-plan. "He boxed well against Zhakiyanov, but I'm not relying on the fact that I beat Zhakiyanov and he lost to him."

Burnett and Conlan are part of a thriving boxing scene in Northern Ireland at the moment, with featherweight Carl Frampton currently the nation's biggest boxing star. Burnett says a future fight with two-weight world champion Frampton is not on his radar. "

"It's unrealistic, he's a little further on from me and a he's featherweight too," Burnett told ESPN. "I can't see myself jumping up to featherweight at the moment -- I make bantamweight comfortably. "But boxing in Northern Ireland is flying at the moment."

Burnett's profile is rising in Northern Ireland and he reckons he get recognised as much now when he is back home as fiancée Lara Milner, who until recently was lead dancer on Michael Flatley's Lord of the Dance show. "She likes to keep fit so she runs with me a lot when she comes over to London," Burnett told ESPN.

"She's left Lord of the Dance now so she can focus on her own dance school in Belfast, she wants to spend more time on that now. "We both pretty much get recognised the same when we are out in Belfast now."
