Is there any chance that it is an accumulation of a number of factors and not just one?
Yes Nuno, he's the boss after all
Yes Fosun, they provide funds and the board, scouts etc to improve the team
Yes the lack of fans, we provide the atmosphere
Yes injuries, we've had more to deal with this season than any of Nuno's previous seasons but that goes back to having the squad that can cope...
Yes Covid and mental health of the players and staff which includes homesickness...
EDIT; and Yes, the players, they put the "plans" into action on the pitch
