Watch the game. It was a pussy move and everything changed exactly with that sub. From being in control and confident, to retreating and absolutely panicking.
Throaters will throat and thats nothing new.
It working against Lecce kind of teams is a different thing. Thats why some are sick of the fraud and clearly sees he must go. We will be punished against good sides with pussy tactics again and again. Anyways, defend it if you like, to me, he was dead as a top coach after that game if not already.
