I had a tactic that was working really well for me. It varied slightly home and away. At home I was more attack minded, with a 4-5-1, with one DM, 3 CMs, and an AMC. On the road I dropped the AMC and played an extra DMC. It worked great and had my 3 points clear in 6th in my 2nd Prem season (I'm Nottm Forest btw). And then, it all collapsed, Went from having the best defensive record in the divison to concedeing 7 in 3. What is the best way to keep a tactic like this and freshen it up?
