I just had a weird cup match today against a team that was playing an irregular formation (2 fullbacks 2 side midfielders and 2wingers plus he didn't have a DC at all just his 2 fullbacks.) I struggled in the match and I only won 2-1 with the goal scored in the 90th minute. Tactics have been hit really hard and the result seemed more like gizzmo said a consequence of the fact that we had similar team quality and maybe because he is 1 level higher than me.
