I would started on normal mentality. If I think that's not wright I choose for Defensive. And you should play down the flanks. You can try in the match play trough the middle. Start first with mixed passes. If you noticed that it doesn't work try long passes. I use 4-5-1 V style with only arrows on AML/AMR. If there nou threat on the flanks I put arrows on DL/DR
I usually go for long passes in that kind of formation, works better.
