They started to improve. As I went easier on power training and saw an increasing performance, my high level super fast learning star goalkeeper still gives me a 5-6-5-5-5-5-5-4-5 performance. I have tried everything. Completely stopped to train him. Kept his morale at maximum. Took him off a few matches to let him recover. Tried to just let him play to get over this down. Nothing. He´s still young but played awesome for me last season. Somehow I still refuse to replace him.
Also I always get the hardest opponents in the cup eliminations. Theres a hundred teams in the cup. You put your finger on the strongest, there you have my next opponent. It´s like someone wants me to early get out of the cup. This may be bad luck but somehow I don´t believe in it´s randomness anymore. Against all odds I´m still there.
But what´s worse is this:

That´s a screenshot of my team AFTER having used an insane amount of reds. For a week now I´m having an injured a day. On good days. On bad days I had two injured in a single match. I have never seen 2 injuries in a single match on the same team for 3 seasons. Now I got this two times. It´s not like I´m playing hardmode on tackles or something. I go for normal training before hardmode generally. I always upgrade the medical section and the green first in my stadium. Also this is after I almost completely stopped to train the guys. This is just ridiculous. If I hadn´t used all those "miracle healings" 90% of my team were injured by now. Has this ever happened in football history? It has literally drained my resources and leaves me with a broken team that´s not improving anymore.
An hour ago was my first match of season 4 which I wasn´t able to attend. A cup elimination match with a new record, 3 injured on my side (add this to the picture). My last goalkeeper got injured in minute 5 with no one left to replace him. Still won that stuff somehow. But a few more days like this and I´ll just delete my account.
