im now playing level 5. for the first 4 seasons I kinda played the same formation. had great success with it. beginning of this season my team were awful. I drew my first 4 champions league group games against much weaker sides. I immediately changed my formation. Things have improved dramatically since. I won my last 2 group matches in champions league to sneak through. now in semi finals with a 2-2 away draw in first leg and 6 points clear at top of league. switched from 4-4-2 with dm to 3-5-2 with dm.
