With the 4 defenders can be enought to protect your goal, change the V for a formation with more men ion the other field, perfectly can work the 4-2mcs-3w-1 that I use starting with attacking mentality +attacking bonus active and then depending of how the match is simulated, in the case that the other plays more in your field switch to defensive. If you have the luck that you can control the match and you wanna keep the result when at same time you are more or less controling the chances, just keep the same mentality and activate the defensive bonus.
