Jake Paul has said that newly-crowned Bellator champion AJ McKee would "kill" Conor McGregor in his prime in his latest social media shot at the Irishman.

McKee won the million dollar Bellator featherweight Grand Prix last night by dethroning legendary champion Patricio 'Pitbull' Freire in the first round of their title fight, and Paul was quick to congratulate him in his own unique way.

The YouTube star and 3-0 boxer took to social media to let his 4million followers know that he felt McKee would "kill 2015 McGregor" after watching him submit Pitbull in his 18th pro fight.

McKee has mentioned that he wants to emulate McGregor by becoming a world champion in two weight classes, having watched the Irishman do it in 2016 by beating Eddie Alvarez for the UFC lightweight title.

But Paul believes that he could end up being even better than the Irishman, judging by his most recent tweet where he likened him to the McGregor that defeated Denis Siver, Chad Mendes and Jose Aldo all within one year.

McKee is a close friend and long-time cornerman of Paul's sparring partner Anthony Taylor, who is a member of the YouTuber's Puerto Rico training team for his upcoming bout with Tyron Woodley.

Paul will face former UFC welterweight champion Woodley in Cleveland next month in his fourth professional boxing bout having turned pro in January of last year.

He is a slight favourite to beat the smaller Woodley, who has never boxed before and lost his last four MMA bouts, including a title fight with Kamaru Usman.

And he has already set his sights on a bout with McGregor down the line, saying that talks are underway and the fight is "90 per cent" done.

"I'm sort of thinking about it one fight at a time," Paul told Maxim magazine in a recent interview.

"Anything is possible after my brother fought Floyd Mayweather, I could fight anybody after this and I think there's a 90 per cent chance of [a fight with McGregor] happening.

"That's the biggest fight that Conor can do. It'd be the biggest payday for him."

Paul has proven an impressive pay-per-view draw in the boxing world, reportedly selling 1.5m pay-per-views for his first round demolition of former UFC star and Olympian Askren in April this year.

And he was also a part of the undercard of the sixth biggest selling fight in history; the exhibition between Mike Tyson and Roy Jones Jr in November.

It was after his win over former NBA star Nate Robinson on that card that he started calling out McGregor, and has been unrelenting since, despite taking on different opponents.

He even flew from his Puerto Rico training base to Las Vegas to taunt McGregor at his most recent bout with Dustin Poirier, sitting cageside wearing a chain depicting McGregor after being KO'd by Poirier in their second fight.

Paul has since gifted the chain, worth a reported $100,000, to Poirier, who says he will auction it off for his charity 'The Good Fight Foundation'.
