Vex made a good point. It all falls back on Suning.
They underestimated the changes that were made to the squad in the summer: Conte walking, Hakimi and Lukaku being sold and Eriksen unable to play for us. Alternatively, they understood and simply did not want to reinvest to reinforce the squad because of their finances. Or maybe it was a bit of both.
I think they felt the changes that were made were relatively minor. Replace Conte with a 3-5-2 tactician, Dumfies for Hakimi and Dzeko and Correa for Lukaku and it was all fixed: we would still defend the Championship we won last season. More than anything it shows how little they understand and know about football and how their lack of investment has hurt the club.
What has happened this season is unsustainable. We have played a full season relying on 14 or so core players (Handanovic, Skriniar, De Vrij, Bastoni, Dumfries, Barella, Calhanoglu, Brozovic, Perisic, Martinez, Dzeko, Darmian, Dimarco, Vidal) with a squad that is so pitiful that the likes of Dzeko, Barella, Calhanoglu and Brozovic can not be rested without the team suffering a significant dip in performance.
And apparently, we need another 70 million in sales this summer. It is only going to get worse because with each sale the squad gets weakened and the replacements are by no means up to standard.
