Do what West Brom did in the '04-05 season

Try a defensive formation, preferably 4-5-1V since that's what I use, and have been undefeated this season. My tactics are defensive, down flanks, mixed, counter force on, low, normal, man-to-man, no offside trap. Down arrow on DMC, up arrow on the wing players. Since your defence is leaking goals, try getting the rightmost goalkeeper from the recommendations, or look a 24+ y.o. second hand keeper with a lot of appearances for the club. I did this last season, and Bava earned us 2nd place after a horrible start. Also give full monetary bonus and train them to 10% bonus in all fields. They are extremely crucial, and try to attend your matches. Also have a chat or two with @Tactician
I assume your target is promotion.
