Currently in the championship with Millwall, I've scored the third highest amount of goals but the joint worst conceded. Any ideas for tactics?
If you're playing on attack mentality you might want to scale back to control, alternatively you might want to add the "Be More Disciplined" instruction.
I don't know what kind of tactic you are playing, but it's usually a good idea to take a look at the goals you concede and try to identify a pattern in how these chances are created. Maybe you are playing too high a line and people get in behind you? Maybe the opponents number 10s are getting too much space and time to pick a pass?
If something keeps popping up as a problem you should then make moves to stop it.
