mass collapse of squad form, as in barely a player has been 6/10 for the season so far, has to be indicative of a wider issue. As in it can't be coincidental. Things i can think of;
1. Burnout and subsequent total lack of fitness
2. Major disruption behind the scenes upsetting the squad, main culprit is potential bad decision from 115 thing.
3. Tactics arent working causing complete lack of cohesion, results, thus confidence.
I don't like number 2, i dont buy it.
Number 1 looks most likely and number 3 is happening because if it (compounding the issue plus dragging newer players down).
I'd say more defence of number 1 is that newer players, e.g. Nunes, Kovacic, Doku, Savinho, definitely don't look as fucked as the rest, but are being dragged down confidence-wise as they cant carry the team. Perfect storm folks.
