Austin McBroom and AnEsonGib are both focused on beating the brakes off each other next weekend ... but they've also got an idea of who they wanna face next -- telling TMZ Sports they're going after KSI and Jake Paul, respectively.
McBroom and Gib are the main fight at the Social Gloves 2 event at Banc of California Stadium on September 10 ... and stopped by the TMZ office earlier this week to talk some serious trash.
Gib says his plan is to "dismantle" McBroom next Saturday and then go for the best .
