Legendary on FIFA17, sooooo many 0-0 draws and 0-1 defeats... Almost 3 seasons in on manager mode and I've finished mid-table each year with less than a goal-a-game throughout the season. 26 goals from 28 games in current season. Have tinkered with tactics, formations, players, etc. Nothing changes... Weeks of goal-less football, then I'll belt someone 4-0, then it's back to bore-draws.
Defensively, no problem.
Not playing an overly defensive game... 4-3-1-2 with the full backs overlapping all the time, etc.
