Anthony Joshua is expecting the toughest fight of his career when he defends his world title against Eric Molina.
Joshua will take on the American in Manchester on December 10 after heavyweight legend Wladimir Klitschko withdrew from negotiations.
And the former Olympic champion is expecting to have to dig deep to keep hold of his IBF belt.
“I am pleased that everything is now set for December 10 and I can concentrate on getting the business done in the ring,” he said.
“There has been plenty of talk about who I may face but all I’m doing is concentrating on finishing Molina in style and putting on a great show.
“Every fight is dangerous in this division and this is no exception. I saw Molina have a great fight with Wilder and he is now coming off a strong KO win against Adamek in Poland.
“I’m expecting this to be the toughest fight of my career so far and I will be ready for an all-out war.”
Klitschko was forced to delay his return to the ring until next year when he suffered an injury in training.
Joshua’s British rival David Price was also in the running but was ultimately overlooked.
Molina will challenge for a portion of the heavyweight title for the second time having been knocked out by Deontay Wilder last year.
He has since recorded routine stoppage wins over Rodricka Ray and Tomsz Adamek.
“There is no heavyweight in the world that has bounced back like I have,” he said. “That’s the man that Joshua faces on December 10 and that man is a very dangerous one.
“He’ll fight the toughest Molina that anybody has ever seen, just like Adamek fought the toughest Molina.
“I’m confident. These type of fights don’t shake me up, I’m a very strong mental fighter. I know exactly what I’ve got to do to prepare myself in the amount of time. I know exactly what I’ve got to do, mentally, physically, to go there and perform.
“When you walk out into the atmosphere, half the battle is the mental battle, and if you can stay in the moment mentally you have a shot in any fight.”
