Considered to use the same formation as your opponent? You don't seem to have any choice, but play with a 3xDC defence. Maybe 3-5-2 flat (with motivated ML+MR)?
Btw, My CUP opponent has a 95% scout team. All of his players are 7* + 4x6* benchplayers. He will use a 4-1-2-3 formation. I will stick to my 4-2N-2W-2 formation ...Kickoff in 45min!![]()
