I'm new to this game, but based on observation...I am worried about your CD coupling.
One on Stopper role while another on Defend. The one with stopper will move forward to challenge...but the one on Defend will not close in to assist/clean up the challenge. You just need two decent ST up front to break this coupling with an easy thru pass.
Also, what bluebird said, based on your instructions...except your back line are playing about your own third, the rest of your team is dancing around at the offensive half. This is effectively overloading, which can yield great goal count as you will capitalize any mistake...however, a simple bunker + quick counter will break your tactic. A quick thru pass from deep over the top, and all your players are chasing backwards...
