The neutral mentality is kinda best. Playing with a 4-4-2 (DL, 2x DC, DR; ML, 2x MC, MR; 2x ST) and I won every game except of 3 until now.
It depends on the opponent too.. For example I have only wins in my league and I have conceded only one goal (!) but in the Champions League I play against tough opponents so I have to use different tactics.
