Anthony Joshua insists he will not make the same "little mistake" against Andy Ruiz Jr a second time around after a lack of patience cost him his heavyweight titles.
Ruiz stunned the boxing world back in June when he stopped overwhelming favourite Joshua at Madison Square Garden in New York, in the process securing the IBF, WBA, IBO and WBO belts.
However, the beaten Briton believes the outcome would have been different had he shown a greater degree of patience after dropping his rival in the third round.
In his haste to get the job done, Joshua was caught himself and sent to the canvas. He was knocked down again before the end of the third and, having never fully regained his composure, eventually stopped in the seventh.
The two will do it all over again on December 7 in Saudi Arabia, though the hungry challenger intends to make sure history is not repeated.
"There's no need to rush. Until the beef is 100 percent cooked, don't take it out of the oven," Joshua told Sky Sports.
"I went to take it out of the oven and got burned. I've got to wait a little more, wait until it's ready and then I'm going to go in for the kill.
"In the last fight it wasn't ready yet, I should have left it in there a little longer.
"It was a little mistake on my part – the good thing is I've got a chance to do it again."
Both fighters were in London on Friday for the finale of a three-day press tour that had already included stops in Saudi Arabia and New York.
Speaking on home soil, Joshua revealed his determination to overcome what he described as a "blip" in the first meeting, with the focus quickly switching to training now media duties are over.
"It becomes fun when you're winning. Now I've taken my loss and am fighting for the championship belts," Joshua said.
"I'm not fighting anyone else – I'm fighting the champion, a serious fighter. I've got to focus. It's a great mindset to have - the minute you lose that, you've got to retire.
"You've got to be hungry. I had a blip – you go again. I'm not shy, no fear. I'm stepping straight back in and looking forward to it.
"To see him [Ruiz] here, seeing the belts and everyone here, it's our last press conference and now we can train, train, train."
