Anthony Joshua admits a future bout with David Haye would be a mega-fight but says his current focus is knocking out Charles Martin and becoming world champion.
The Olympic gold medallist meets Californian southpaw Martin at London's O2, live on Sky Sports Box Office on April 9th, as he bids to become IBF heavyweight champion of the world.
Joshua spoke to Sky Sports News HQ on Monday and was asked what he thought about being called out by a number of heavyweights, including former WBA champion Haye, who returned to the ring in January after a three-and-a-half year break.
"Bring it on," Joshua said.
"My heart tells me I'm ready to rock and roll. After 16 fights, I'm at championship level now but I have April 9 to get out of the way.
"I'm going to focus on that as usual and then moving forward David Haye is definitely someone I would consider and take seriously.
"I'll do it when I'm ready and he's ready and it will be a mega-fight. I'm looking forward to more competition like that at world level."
Asked whether he is looking for a knockout win against undefeated 29-year-old Martin, Joshua said: "Yes, because I want to display my punching power and my accuracy.
"I wouldn't do it in a reckless fashion without composure. This will be composed and calculated and when I see the opportunity I am going to capitalise on it.
"I want to be able to show what some people call a 'professional novice' can do to a world champion. That's why I want to knock him out in good fashion."
Joshua's world title challenge comes after just 15 fights since turning professional in 2013. If he wins, he will have become a world heavyweight champion in fewer fights than Muhammad Ali, Joe Louis, Wladimir Klitschko and Lennox Lewis.
And Joshua is convinced that provided he can beat Martin on April 9 and continue in the same vein, he can become one of the true heavyweight boxing greats.
"If you asked me two years ago I would have said 'no' but as time goes on I am building up more confidence," he said.
"As long as I keep on winning, of course I am heading in that direction but first and foremost I need to secure those wins.
"But looking to the future, if I stay on the course that I am on, I can definitely see myself alongside some of the greats in the boxing."
