Anthony Joshua says he'll make anyone who challenges him, including Kiwi Joseph Parker, look "rubbish".
The British heavyweight boxer will face Parker in a mandatory IBF world title fight, with plans for the bout to be revealed in November.
Joshua retained his IBF world heavyweight title by knocking out American fighter Dominic Breazeale in London at the end of last month.
And while Parker prepares to face Australian veteran Solomon Haumono in Christchurch next Thursday, Joshua awaits his next challenger.
The 26-year-old Brit admits he doesn't mind who he fights next, after saying he wants a serious contender before November, but whoever he does face, he's out to make them look "rubbish" in the ring.
His next opponent could be former world champion, Haitian-born Canadian Bermane Stiverne, who revealed he was "in camp" ahead of a potential bout with Joshua, with no official confirmation coming yet.
"There's no-one lined up currently but I'm sure they're looking at the horizon and lining up some serious contenders," Joshua told Sky Sports.
"I don't actually mind [who it is]. Anyone really. I don't have anybody specific that I dislike or need to fight. It's all part of the longer journey. My job is to make them look rubbish and make them look easy."
Joshua, who's won all 17 of his professional fights by knockout, did reveal he wants his next fight to be staged in the UK.
Heavyweights Deontay Wilder, David Haye, Jarrell Miller and David Price have called him out, as well as Parker.
"It has to be [in this country]," Joshua added. "This is the hot property right now and we've got about 13 champions in the UK so everyone wants to be here fighting.
"I want to get out in November. I want to watch these guys in the Olympics and then get back in intense training and start preparing for my next fight."
The Brit's next bout could be with former WBC heavyweight champion, Stiverne, who told Sky Sports he was ready for the call to face Joshua.
The 37-year-old's record from 28 professional fights is impressive with 25 wins, 21 by knockout, with one draw and two losses.
I'm actually in camp right now," he said.
"Getting ready a little earlier will not hurt me - better to stay ready than to get ready when I get a call.
"Everybody has been talking about the possibility to fight Joshua, you know. That's option No 1, I'm available, and willing to fight.
"[Joshua's representatives] have been going back and forth with [promoter] Don King but I don't have any details about the conversation. The last conversation I had with Mr. King, I told him to make it happen.
"I have a desire to be a two-time heavyweight champion. All I'm waiting on is the call."
Stiverne is based in Las Vegas and he won the WBC title in 2013, after it was vacated by the retiring Vitali Klistchko, when he defeated Ray Austin.
He then lost the title in January 2015 to unbeaten American fighter Deontay Wilder.
