Dude obvviously your opponent is not a tactical genius (who plays with one DC??) refer back to a standard backline with 2 fullbacks and two centre halves (play with DL&DR and two DC's) I would suggest you stop playing with wingers and have a try with AMC's. I'm in level 24 and as I have progressed in the game I have discovered wingers are only useful in the lower levels. Just go with the Attacking mentality and force counter attacks make sure all your starters are 5 stars and watch the game. You can choose hard attacking later in the game if you wish too
