For the last few weeks, WBC heavyweight champion Deontay Wilder and WBO champion Joseph Parker have taken their verbal digs at Anthony Joshua, who holds the IBF, IBO, WBA belts.
Both Wilder and Parker are going after Joshua (20-0, 20 KOs) as their next opponent.
Now it's Joshua's turn to get in some verbal punches as he responds to both of his heavyweight rivals.
On Wednesday, Parker and his promoter David Higgins of Duco held a press conference to illustrate to the media that Joshua had a "glass jaw."
Joshua was scratching his head after watching the press conference footage.
“Parker is investing his time in the wrong areas,” Joshua said. “Does he want publicity? It it a PR stunt? It's not about worrying about how we fight. I fought Wladimir Klitschko too early but the opportunity came and we managed to come together with one of the all-time greats, we put on a show with no complaints.
“So what is so difficult about fighting this little kid who is doing press conferences? It's very unprofessional of them. The heavyweight championship is such a respected title to have but stuff like that takes away from the crème de la crème of the title."
In terms of fighting the rival champions, the British star believes he would stop both men.
Joshua is confident that he would knock Wilder (39-0, 38 KOs) out clean with a single landed power shot. Parker (24-0, 18 KOs) is another matter. He feels the New Zealand boxer would need some additional chipping, round after round, until his chin breaks down.
“I think I know what I have to do with Wilder,” Joshua said.
“Parker? I don't disregard him but I think I'd smack Parker around the ring, no problem. Wilder? I'd knock Wilder out, it would take a bit of time but I'd definitely knock him out. Parker would take a bit more of a pasting but I'd get to him. Wilder, I'd knock him out with one shot. Not like I'd go in there and bang but when I catch Wilder, I'd definitely knock him out.”
