The Samoa-born boxer Alex Leapai is talking tough after signing on to fight Wladimir Klitschko for the WBO heavyweight championship title.
Leapai will become just the second Samoan boxer to fight for a world heavyweight title, 14 years after David Tua was beaten by Lennox Lewis.
The 34 year old was born in Samoa and lived in New Zealand for eight years before moving to Australia, the country he now represents.
He cites Tua as an inspiration and believes he can win the fight.
"It will be a dream come true and it's all about reaching that goal and proving it to the kids out there that anything is possible. I've done a lot of bad things in life and to be able to turn it around and never once dream that I was going to be fighting the world championship, held by these guys like Muhammad Ali and Mike Tyson. But for me it's not about the money and I promise you guys one of us is going to get knocked out but it ain't going to be me".
Leapai earned his tite fight with victory against the previously undefeated Russian Denis Boytsov in November.
The fight is in Germany in April.
Wladimir Klitschko has won 61 fights, 51 by knockout, with his last defeat coming almost ten years ago against Lamon Brewster.
