"I'm not a major historian so I won't reel off every fight I've watched but I've watched a lot. I don't do it because I want people to respect me. It's not complicated. It's my job, an opportunity to make a living. It's a blessing. These are the best days of my life. I started in 2008 during a global financial crisis and not a lot of people were able to invest in sport. So it's been a blessing to get this far. I promote boxing not to be famous but so that everyone can benefit from it."
"I wasn't involved long enough in the amateurs to really know Usyk, but I've done my research. I've the utmost respect for him and Papa-chenko. They love boxing like I do, and I love the Ukrainian people. The cream always rises to the top, and we're both here now. Good luck to them."
"I'm happy to be back. I'm very excited about this. You've got to want to train, improve, put the work in. When I started boxing it was fun because I was s--t when I started. Then I started beating up the guys that were giving me problems. When you see improvements, you want to do more each day. I hope everyone enjoys fight week but for me this is another day in camp. I'll be back in the gym next week."
Clad in a dazzling red suit, Usyk gives via interpreter a deliberately short answer to Hearn's first question, before laughing. He then says: "I feel fine. I look forward to this. I'd like to thank Eddie Hearn and my team. I'm grateful this is happening."
"Usyk is as good as it gets. It's a fight that should happen and AJ will fight anyone. This is an absolutely brilliant fight for the world of boxing. Joshua has trained really well and we're really looking forward to it."
"Joshua has the heart of a warrior. I thank him for accepting the challenge of Usyk. I also commend Hearn for his professionalism throughout. The only way to get the things you want in boxing is to fight the best. To dethrone the king. And AJ is the king. Let the best man win."
"To say I'm delighted to be here is to say nothing. Such a huge fight. Those guys are two Olympic champions from London, facing in London to learn who is the best man. With all the fights cancelled this year, I still cannot believe this one is happening but it is happening Saturday.
"From Bruno to Tyson to Naseem to Froch-Groves. We've really enjoyed working with both Joshua and Usyk as great British boxing continues. The atmosphere on Saturday will be second-to-none. It's brilliant to have fans back in their thousands."
"Whether you're a casual or hardcore fan, this is a truly great fight. A former undisputed cruiserweight champion jumps right into the fire against the heavyweight champion. And it wouldn't be an AJ show without a very well put-together undercard. Good luck guys."
We are awaiting the arrivals of Joshua and Usyk on the hour (2pm BST/9am ET). The undercard fighters have had their head-to-head press conferences, with Florian Marku being at the centre of a bit of a scene in particular.
