Anthony Joshua has vowed to "walk through Tyson Fury" after winning the IBF world heavyweight title following a second-round knockout of Charles Martin at the O2 Arena.
Joshua needed just one minute and 32 seconds of the second round to end the American's reign, but his emphatic performance, his 16th KO in 16 fights, did not impress Fury.
Speaking on Twitter, Fury described Joshua's fighting style as "ponderous" and called for the chance to "slay that lamb".
He tweeted: "So AJ gets a belt, looked slow ponderous, and still looked like a bodybuilder, let me slay the lamb."
But Joshua has no qualms about facing up to the reigning WBO and WBA champion. In fact, the 2012 heavyweight Olympic champion is pretty confident he can continue his unbeaten run against his British counterpart.
The 26-year-old told BBC Radio 5 live: "The promoters are going to do their promoting, the fighters are going to do their fighting and the public are going to do their talking and I'm going to keep on walking.
"I'm going to walk through Tyson Fury when's he's ready. I'm not messing around believe you me.
"Scrap all this 16 fight nonsense. I'm training hard and I mean business. I'm here to stay and I want to make some real noise in this division. That belt. I got big respect but I want to do more. If I get too carried away I feel that I'll get complacent. So let's put that bad boy away.
"Let's put that with the Olympic medal and let's go on and get more and keep entertaining these boxing fans. That's what I'm here to do. I'm young, I'm fresh and honestly I'm looking forward to getting back in the gym.
"I have got skill. I'm not just some beach body boxer. I train hard and this is just the results. IBF champion and I'm very, very happy. I'm happy for the UK as well."
