Play 4 back still but you wont need the dmc. I will go with 442 or like yours 43n 2w 1. If you play that, make sure your highest def rating mc goes in the middle and your attacking mcs go on the sides.

Also, dont play attacking mentality with counter attacK. counterattack is where you give the ball to the opposition, then when you win the ball back hit them on the break when their players are outta position. The key is winning the ball back after you give them the ball so usually defensive counter attack or normal but not attack. I have scored 8-0, 9-0 playing defensive counter attack. There is no need to go attacking mentality to break through their non existent defence if you cant win the ball back.
