Logan Paul wants a rematch with Floyd Mayweather ... and the YouTuber turned boxer says he's sure Money's gettin' his ass knocked out this time around.
TMZ Sports talked to Logan at a media event for his bro Jake's upcoming boxing match with former UFC champ Tyron Woodley ... and when we asked Logan if his bro would ever fight Floyd, LP said it's him who wants the fight.
"Let me ask you what you would rather see, Jake Paul versus Floyd, or me versus Floyd again?" Logan said. "Because, let me tell you something, if I fight Floyd again, I promise I’ll knock him out. Promise."
Remember, Logan and Floyd fought an exhibition fight June 6 in Miami ... and the fight went the full 8 rounds. No winner was declared.
This time ... Logan suggests they fight more rounds -- and he says that won't bode well for Mayweather.
"I got it figured out. I got it. End of the 8th round, he’s breathing heavy, I’m coming alive. It’s gonna be a 10-12 round fight. We run it back, and this time I finish him."
Now ... will this happen? Even Logan says probably not.
"I don’t think it’s gonna happen. This is all just hypothetical bulls***."
Still, LP had a message for 50-0 Mayweather ... "Hey Floyd, loved the opportunity, would love to run it back sometime. If you’re feeling up for it champ."
