I made a screenshot for you of a strong defence team having a higher level (Lvl5) than me (Lvl4) which I beat 1-4 on away game for the cup playoffs few days ago. Even with a strong defence I focused on the wings and choosed to focus passing from both flanks with MC - AMR - AML - and ST as red and having blue my DCs , DMC , DML , DMR , with a formation of 2-3-2-2-1 shown in the screenshot.
I hope this is usefull for you, GL!!
