The name Anthony Joshua has dominated the boxing headlines of late.The 2012 Olympic champion recently took his impressive professional record to 20-0, defeating Carlos Takam by TKO in Cardiff.Now, the onus is on his promoter Eddie Hearn to sort out some mega-fights for the hottest property in heavyweight boxing.The two names dominating the narrative right now are WBC champion Deontay Wilder and the returning Tyson Fury.However, one name that is often swept under the carpet is WBO heavyweight title holder, Joseph Parker.The New Zealander recently defeated Hughie Fury on points to retain his title and is certainly worthy of being a contender to fight Joshua.Parker himself has called out the British fighter in the media but on Thursday morning, AJ responded in pretty spectacular fashion to his threats on Twitter.

AJ'S SUPERB TWEET TO PARKER

Well, that'll either spring him to action or has completely called out his bluff.

The main source of the trash talk between the two actually came from Parker's trainer, Kevin Barry, who launched a scathing attack on Joshua's credentials as a top competitor.

BARRY TEARS INTO AJ

"I know for a fact he's been down in sparring [at] a number of training camps," Barry said to News Hub.

"We like the fact that his chin is very suspect compared to Joseph Parker's chin. Joshua has come out and said different guys have dropped him in sparring with 18 ounce gloves on.

"Stoppage [of Takam] was very, very promoter friendly. His stamina is still lacking. I think he looked very, very gassed towards the end of that fight. There wasn't great speed in his punches.

"In fact I thought he looked very robotic and I thought he looked very slow, and everything I saw made me really excited for when we do eventually get into the ring with this guy."

PARKER STATES HIS INTENT TO FIGHT JOSHUA

The New Zealander recently clarified in a press conference that his main intention is to fight AJ for his WBA and IBF belts.

"I want to fight Joshua. He has got two belts and I want to test his chin and put on a great show," Parker said.

"Those [other] fights would be good to keep busy, but the ultimate fight is to fight Joshua. He is the preferred option for us."
