Considering that your level 13, you should have enough experience to figure why you are under-performing this season. Since you won the Triple Crown last season I guess you are no slouch. Is there anything you are doing differently? Any win bonus adjustments made or counter-formations you use?

I'm not in as high level as you but I have a suggestion, you could look at the new players you signed and look at their attributes and see if they are suitable for the position they play in.

Other than that you could change your captain order, It may not help much but if I think my team is underperforming I always change captain order because it makes me feel like I did something to alleviate the situation lol
