Jake Paul doesn't step in the boxing ring for another three months, but he's already got his sights set on his next opponent after Nate Diaz ... and it's none other than Conor McGregor!!
The Problem Child -- who's fighting Diaz on Aug. 5 in Dallas -- laid out his plans to Babcock on the "TMZ Sports" TV show on FS1 ... saying he fully intends to knock Diaz out (something Conor never did), and then lock in a fight with Notorious.
