Don't know either of these fighters, but did a quick eye test. Acosta looks like another fighter who decided to fight because he's big. No striking skills, gets tagged a lot, and uses his big body weight to try and overpower his opponents. Delija is the complete opposite. Solid striking, looks for takedowns, and strong ground and pound.

This fight is not even close and will end early. I'm taking Delija for -105.
