Hey guys, I am playing a 4-4-2 diamond in my Palermo career for a few seasons now and I am starting to have some issues down the flanks, even though I have very good full-backs. I know that defending the flanks is the biggest flaw of this system, so I am thinking to add more strenght to this specific area. I just got destroyed by Sampdoria 5-1 and I noticed that every single one of their goals came from the flanks more or less.
My question is this: How can I instruct my 2 CM's to close down their respective flank alongside the full-backs ? What I basically want is that my CM's to start pressing in tandem with my full-backs when there is a threat down that specific flank.
