WBO heavyweight champion Joseph Parker (24-0, 16 KOs) is very motivated, as he heads over to the UK to join his promoter David Higgins - who is in the process of finalizing a deal with Eddie Hearn for a unification showdown with IBF, IBO, WBA champion Anthony Joshua (20-0, 20 KOs).

Once the deal is complete, which many expect to happen this week, the fight will take place on March 31 at Principality Stadium in Cardiff, Wales.

"It is life-changing, not only for myself but for my parents and my family. It's been a great team effort to get to this stage and I pay tribute to my management team, and my parents, my legal team. Not many people realise what is involved with something like this, it's so big and complicated. There are so many people to say thank-you to," Parker told Stuff.

A few days ago, Hearn issued a warning that Joshua was very irritated by all of the trash talk being done by Parker and his team members over the course of several months.

Parker, Higgins and even head trainer Kevin Barry have been very critical of Joshua's wins, Joshua's ability to take a punch, and they labeled Joshua's style of fighting as "robotic."

According to Hearn, Joshua could very well break his nice guy character and explode with verbal fury at the first head to head press conference.

Parker has no fear of an angry Joshua.

"Listen, I'm not scared of the guy. I don't care if he's angry or not, that's part of the game. We've had to be aggressive to get it to this point," Parker said.

"If he has any issues with what has been happening in the media and that sort of stuff, that's up to him. He should be able to accept the different challenges in boxing in terms of physical training, how people talk and what people say. So if he's angry, so be it. He can get in the ring and try and bash me around. I'm going there to knock him out cold.

"I feel he is a great fighter, I have a lot of respect for him and he has great power. But styles make fights and I feel like his style matches me perfectly. I have a lot of confidence in myself. It will come down to the day, who is taking the hardest hits and who has the best day that day."
