well no one answered, but I played 3-4-3 attacking trough flanks. short passing, pressing whole pitch, offside trap ML/MR red arrows..
I managed to win 1-0 but it wasn't enough..
I'm up against a strong opponent using the same formation. I'm thinking of 4-4-2. red arrow on both STs / blue on all 4 defenders /normal mentality / attack down the flanks / own half /mixed pass / counter attack. will post the result later.
