Cup final: How to beat 4 Star stronger 3W-4-1-2?

[Wohltat]

Hello,

I made it to the Cup final and now I face a stronger team (Level 3 vs. Level 2). He is playing 3W-4-1-2 and the suggest formation against that is 4-1-2-1-2 Narrow Diamond. Unfortunatelly, my best offensive players are my AML and AMR (~28) while my AMC is only around 20. Another issue I have is that my defense sux a bit in comparison to his offense. Any suggestions? If Narrow Diamond, which orders and arrows?

PS: I will watch the game with two friends and get 9% ball possession bonus if he does not watch...
