Whenever I use my own tactics on this game I seem to have a real knack for creating a brick wall at the back. I always seem to do brilliantly defensively and rather badly offensively. I recently started a save with Man Utd and after 15 league games I've only conceded 3 goals. I don't think I've ever had a defense as solid as this before and was wondering what the smallest amount of goals conceded in one season was?
