Looking for tactics help!

Hi All, I'm looking for any help possible with tweaking this tactic I am using with Athletic Bilbao, I like the formation and the roles but open to suggestions. Just wondered if anyone out there knows of any other way I can dominate games (and particularly to score goals!) within this formation

Attached are images of the overview, team instructions, and each different player instruction (didn't know how to put them within the text)

Thank you to anyone that can help
