Paul has spent a six-figure sum on the new necklace commemorating McGregor's first career knockout
The YouTuber, who recently took Floyd Mayweather eight rounds in their exhibition bout last month, has been an earnest critic of McGregor since the Irishman called him and his brother “dingbats”.
Paul has spent a six-figure sum on the new necklace commemorating McGregor's first career knockout, with a figure representing him lying unconscious in the octagon after his last fight.
Jake took to social media as well, to claim the Crumlin man has lost his edge.
"You can tell Conor has lost 'it'," he wrote on social media last night.
"He no longer speaks from a place of authenticity and you can tell he’s trying to convince himself of his own lies.
"He takes offence to everything now; he’s bathing in his own insecurity’s [and] when we fight I will further expose him for the fraud he is."
This is just the latest in a series of insults that Jake Paul has aimed at McGregor which included one video when he branded the legendary UFC star an 'Irish c***' while draped in the tri-colour flag.
He also insulted McGregor's fiancée Dee Devlin, who is mother to McGregor's three children Conor Jr, Croia and Rian.
“My team sent you a $50m offer this morning – $50 million cash, proof of funds – the biggest offer you’ve ever been offered," said Paul in the viral callout.
"But you’re still scared to fight me, Conor. You’re ducking me because you don’t want to lose to a f***ing YouTuber.
"You’re 0-1 as a boxer, I’m 2-0 as a boxer, I just came off the eighth biggest pay-per-view event in history, but you want to fight Dustin ‘Prober’ [Poirier] who has less followers on Instagram than my f***ing dog – that’s a fact."
When asked this week about taking on either sibling, McGregor replied: “Never say never, if they're going to keep competing and whatnot, who knows? They're dingbats, the two of them.”
Conor McGregor and Dustin Poirier will clash for the third time in the main event of UFC 264 in the early hours of Sunday morning.
The two first met in the Octagon just over seven years ago at UFC 178, where fresh-faced McGregor claimed his third UFC win with a knockout in just under two minutes.
The latest instalment was held in January this year, on UFC's Fight Island in Abu Dhabi. On that occasion, it was Poirier who knocked out McGregor, the first man to ever do so in MMA.
