I am Ipswich of course and ive just got to January in my first season and im really struggling but its strange because after about 10 games i looked very good and i was 3rd but i think ive only won 1 since. Im using same tactics but i look awful and im lucky to draw any match! All help would be much appreciated.
i remember once this happened to me, i started well but my team started to get shaky. but i had bought 2 players from the swedish league and it ends around end of november. So they came and made the difference, i started to slightly well. And when they got settled the team did much better.
I went off to fight into the play-off and end up as 3rd. And won the play-offs

So i think if u have had a good run in form before with a tactic. then u should just be able to pick the right players. get 1-2 more players to add more depth and DIFFERENT quality into the team.
And alter the tactics slightly according to the oppositions and such, and you should be able to pick up more and more.
try to also try a few small things as well. Maybe new set plays tactics etc? things like that make a difference.
