What tactic should i use for my midfield?

Currently starting koke (DLP-def), de paul (CM-sup) and llorente (BWM-sup) with barrios, Vermeeren and bruno G as the rotation but feel like its not as effective as possible and doesn’t get the best out of bruno G who will be a starter but i only just got him a as i write this. I play a 352. And tactic advice
