Classic 4-4-2 (DL-DC-DC-DR--ML-MC-MC-MR--ST-ST) is played with short passing, attack over the wing, pressing the own half, no counters, no offside trap. The rest is up to you. Personally I go for normal tackling, since with hard tackling you get too many cards and soft tackling is too soft and I usually play it with normal mentality (but that is individual choice).

Another system you can play with your rooster is 4-5-1 V-style (DL-DC-DC-DR-DMC-MC-MC-AML-AMR-ST. That is a counter formation system that focus attacks also on the wing, but is played with mixed passing since you want to counter your opponent (fast with a mix of short and long balls).
