I really need help!

I haven't won a game since the start of my second season. I am using the tactic that brought Hertha BSC from promotion to 6th place; I thought I was doing well. I made some signings and got Arjen Robben on loan, and was hoping for another mid table finish. I have played every game with no success so far. My players are all in really bad moods and they get injured every day. They complain about there workload and I give them a lighter routine with no success. What am I doing wrong? I would take screenshots but I don't know what's important for you guys to see.
