"2019 was cool," Masvidal says ... "But, if you like violence, 2020 will be a very powerful year. We’ve got a lot of options. I've got a lot of lottery tickets in my hand."

Masvidal -- who demolished Darren Till, Ben Askren and Nate Diaz in 2019 -- says his goal is to fight Conor in April or May ... and then take a boxing match with Floyd in November.

As we previously reported, Mayweather has a handshake deal with UFC president Dana White to box an MMA fighter in 2020 and we're told he's eyeing fighters with top stand-up striking talent.

Masvidal obviously has those skills and firmly believes he's the frontrunner for that fight.

"I can box my ass off," Masvidal says ... "Not saying I’m a better boxer than Mayweather, but man, I’m gonna be in there with bad intentions trying to hurt him."

The last UFC fighter to take on Floyd was Conor McGregor who famously gassed around the 8th round with the ref ultimately stopping the fight in Round 10.

"I'm a well-conditioned athlete that’s not gonna fade," Masvidal says ... "I'm not gonna fade in the 8th or 9th round. I’m gonna be there for the whole night."

Jorge -- who's calling the big Tito Ortiz vs. Alberto El Patron fight for Combate Americas on Saturday -- also had a message for Floyd ...

"If you’re looking for a fight, I’m right here. If you’re looking for an easy paycheck, go back to Japan and beat up those little guys."

Masvidal says he understands why Floyd would be interested in someone like Khabib Nurmagomedov ... it's easy money for Floyd ... but if he REALLY wants a challenge, he'll sign the contract with Jorge.

The video is great ... Jorge knows Floyd is obviously much more experienced than him in the boxing ring, but he truly believes he can get the best of Mayweather and spells out his case on camera.

Think about it ... if Jorge's plans come to fruition, he can make LIFE-CHANGING money in 2020.

The Conor fight alone is big money ... and a Floyd fight could earn him more around $100 MIL.
