Ok. What tactics you use? Do you change tactics when you change formation, if yes, then how?
Your players form is good (besides last match or 2) so it shouldn't be problem. Maybe something else is.

Bad start doesn't always mean that season would be bad.
This is example, last seson of mine team which was inactive in 1st week (I didn't open TE at all), then I reactivated it and managed to climb on the table up to 2nd place
