Paulie Malignaggi has branded Conor McGregor the "king of bulls***" amid reports the pair have held talks about a potential fight.

The fighters have a chequered history having sparred before McGregor took on Floyd Mayweather in 2017.

The Irishman released footage which he claimed showed him dropping the former boxing world champion.

Malignaggi disputed the claim and left McGregor’s training camp.

The pair have since been embroiled in a bitter war of words with a fight between them seemingly inevitable.

Indeed reports surfaced earlier this week suggesting talks had already started – something Malignaggi has denied.

“Conor is the king of bulls*** so I would not be surprised if this is Conor having his team put out rumours just to keep his name in the headlines,” he told the Daily Express .

McGregor is currently awaiting a ruling as to the brawl that followed his defeat by Khabib Nurmagomedov last October.

The Nevada State Athletic Commission will decide his punishment on January 28 with McGregor facing a ban and a fine.

He could return to the UFC in a rematch with Nurmagomedov, or face Dustin Poirier in a bid to land another title shot.
