A 21-year-old fighter drippin' in Conor McGregor swag says he's the guy to kick CM Punk's ass next -- and he's willing to do whatever it takes to make it happen.
"Dana White, if you're listening ... I'll put up my entire paycheck if I don't knock him the f**k out," Matt Bilella Fitzpatrick said outside 1OAK in L.A.
FYI, Punk got wrecked in his debut at UFC 203 ... but there are rumblings the WWE superstar's gonna get a 2nd fight sometime next year.
Matt says he's the man for the job ... and he ain't all talk -- kid trains at the same MMA gym as UFC superstars like Jon Jones, Holly Holm and Donald Cerrone in New Mexico.
