Counter-attack and NO offside trap, you can use focus mixed but I myself prefer both flanks. It also depends on your opponent's formation, if he has strong DL/DR and ML/MR then I switch to mixed passing or through the middle. If he has strong DMC and DCs, or he has 3 MCs and no ML/MR, then I go for attacking down both flanks.
This is a defensive formation ... It's better to play defensively with counter attack. For my team, usually whenever we counter attack, we score.
