So you play 451v, arrows I use red on DL Dr if opponent are weaker or same quality and also if he's wingers are no treat, also always use red on Aml AMR as this will be your attacking focus, and blue arrows on DMC and both MCs( these are optional) orders will depend of your team but always down the flanks and never offisides trap as you have too many players at the back, and you can play defensive with counter on or attack without counter up to you I play 100% low press and zonal marking, also normal tackling.
