I would definately suggest you to check if you increased the winbonus for your players.

I am in my 10th season now, and won most of them......(I buy scoutplayers, use tokens to increase building speeds, the works) anyways, The few matches that I did lose were directly to be linked with the fact that I had forgotten to adjust the win bonus starting a new season.

For as far I can see, the results of your team varies, on various factors, Offcourse the obvious things, like teamquality, good formations, smart training, analying your opponent and stuff like that. However, win bonus has a huge impact on wether your players, In my case a lot of scout players, and or highly skilled players, or youth players, actually feel motivated to move their butts on the field.

Ive had troll scores, (for which at first I blamed Nordeus for lol) then I realized I hadnt adjusted winbonus , for like 2 seasons allready lol.

These days I just max it out, I realise if I would daily adjust it to depending how strong of a team I am playing I would gain more financial gain, However , at this stage I am doing pretty well financially, without money investment due to prize money, good sales on players (even made huge profit on 1 28 yr old 2 footed striker , which I had bought for 17,5 and sold for 37.)

Maxing out on wnbonus might seem like a lot, but it ensures good results, or prevents bad results , take it how you see fit. As club throughout the season I make about 1/3 of the prize money. However, I get pretty far in the CL and Cup and have only failed once to get the 1st place so far, Ended that season 3........because I had lost for not setting win bonus.

Playing friendlies helped me find this out...
I hope this helps you to start kicking butt and taking names again.......goodluck.
