Former heavyweight champion Evander Holyfield wants another world title shot if he beats Denmark's Brian Nielsen on Saturday.
The 48-year-old American (43-10-2) will take on the Danish veteran in a non-title bout at Copenhagen's concert hall.
Arriving in Denmark on Sunday, the four-time heavyweight champion insisted he would not be fighting if he wasn't ready and he was fully focused on the task in hand.
He said: "If I win, I am moving to the next level. I am hoping to get a championship bout with other guys with other belts.
"Back then when I was young, I made a lot mistakes but I had the stamina and all that to overcome.
"Today, you have less stamina but more focus. Either way you go, if you play with what you have, you win."
The fight had originally been postponed to allow Holyfield more time to recover after he was cut above the left eye by an accidental head butt during his fight in January with Sherman Williams, with this bout being ruled as a no-contest.
Before that, the veteran knocked out Francois Botha after losses to Nikolay Valuev and Sultan Ibragimov.
Ahead of Saturday's clash, Nielsen (64-2, with 43 KOs) acknowledged that Holyfield is the favourite but promised the fight will not be a walkover.
"I know that he will be really tough to beat, but he won't meet someone who will throw himself onto the floor before him," he said.
"I will fight until I cannot stand up any longer.
"I have fought 200 fights and I have never been knocked out, so why should that happen now?"
Nielsen, who lost to Mike Tyson in 2001, last fought in 2002 and retired soon after because of a knee injury.
The Dane won the IBO title in 1996 when he stopped Tony La Rosa in the second round. He also ended 47-year-old former champion Larry Holmes' hopes of a winning another belt in a successful title defence a year later.
He added: "It's two old boxers meeting. We are getting older, there's no doubt about that.
"It is an old boys fight, but I believe we can give more than some of the youngsters can."
