Dunno if this helps but I ALWAYS suffer a few bumps in the campain at 2/5ths through the season. I start the season strong, and get the results I would expect (Including some losses against expert managers) but after about 8-10 days into the season I get whacked with 2-3 unexpected losses. Naturally I question my tactics and what im doing wrong. Its frustrating but my team always gets out of the rut within a few days and starts getting expected results again. Just don't go crazy and change up your formations to quickly. Breathe and get through it
