3dc is the right approach...
if you want to exploit lack of dr..dl......put an amr...aml
Id try 3n-2w-2n-2w-1 (3dc...dml..dmr..2mc...amr..aml...st) OR 3n-1-4-1-1 (3dc...dmc...ml..2mc...mr...amc..st) depending on the personnel you have.
normal or attack(depending on the match situation)....pass thru flanks(for 3-2-2-2-1) or mixed (for 31411)...normal tackling...high press...offside off....counter ON(for 32221).
