If I were in the same league, I would do that. However, this is CUP, but I did check his previous matches, all using different formations
I'm thinking you were probably the losing team on the right in your screen capture? Awesome team. But I see a yellow card, and no Defensive Wall SA, I'm thinking thats probably where he scored, probably with that world class player.
I did notice recently that playing the same formation as the opponent will most likely end in a draw, just recently in the scoreboards.
Anyway, I think I will go with 3n-5-2 (Normal), might motivate the wings later (since my ML/AML, and MR/AMR are both shadow strikers, dont think they can do much from midfield.
