Last match I played versus worse team...cuz my DMC had red card I decided to play 4d-2m-2amw-2s with long pases thru flanks and I was loosing 0:1 at half time so I changed to 4d-3m-2amw-1s with short pases and I ended up winning 5:1...also my possesion went from around 50% to 80%...
So I guess formation does matter...
