Put red arrows on your DL,DR,AMR,AML. Put blue arrow with your DMC. The rest of your players have no arrow. If your opponent has a attacking team, you play defensive mentality. And if your opponent has only 2 wingers such as the 2 fullbacks (DR and DL), set the Focus Passing on both flanks,pressing style-Own Half,Tackling-Normal or Hard Tackling(optional),Passing style-Long,Marking Style-Zonal, click check the Force counterattacks, and finally NO-play offside trap.
