Perharps everyone just gave all of their energy, their best into last season and they have little left for this year.
I don't think so. We have a very young squad and we are still in October. Something was done horribly wrong during the preparation for this season. Additionally, players had a long summer break so they had more than enough time to recover. IMHO there are only two possible scenarios:
1. Our training sessions are either inadequate, horribly planned or too intense so players are exhausted.
2. Players were fooling around during the preseason and now they are paying the price.
I am 99% sure that this has nothing to do with bad luck. There are too many injuries for that.
