Anthony Joshua said he knows he 'must win' his rematch with Oleksandr Usyk and insisted: 'I like the pressure'.
Joshua's highly-anticipated rematch with Usyk is set to take place in Saudi Arabia on August 20.
The former two-time unified heavyweight world champion - who had previously only ever lost to Andy Ruiz Jr - dropped a wide unanimous decision to his Ukrainian rival at the Tottenham Hotspur Stadium last September.
But Joshua, 32, will have the chance to win back the IBF, WBA and WBO heavyweight world title belts when the pair come to blows for the second time.

And he insists that he has left no stone unturned in his preparation for the rematch after making several changes to his training set-up.
He said at the pre-fight press conference: "Must win. I like the pressure.
"It's been tough, Robert Garcia, Angel Fernandez and previous existing members of my team as well have pushed me and challenged me, but mostly yeah it's just get the job done.

"Instinct, stay focused, get the job done, God willing, victorious."
At 32, Joshua arguably still has at least a few years left in him before he retires from the sport.
And he said that passion is still burning bright as he looks to keep his career alive despite the overwhelming odds that are seemingly stacked against him.
He continued: "It's competition right? You set a goal. I've got goals I want to achieve in the ring on the night.

"I'm going to be disciplined enough so I can follow them through. So yeah that's like competition with myself.
"And as you mentioned about the belts, they mean something but that's all at the end of the target, so it's not like I'm skipping the process so I'm focusing on the process.
"Yeah, 100 per cent. I'm looking forward to it. I want to compete so I'm looking forward to it.
"I can't really say much else, you've got to have a competitive spirit, so I'm looking forward to competing."
The biggest talking point of the press conference came when Usyk randomly burst into song after the faceoff.
Only time will tell if AJ gets his revenge on Usyk. If the press conference is anything to go by, there's a plenty at stake for both.
