People complain about why Conte didn't make any subs. Against Sassuolo people complained why Conte had made particular subs. After every negative result, people complaining about subs because it's easy to criticize when the game is over.
Miha made 3 subs one of which was 38 years old Palacio. They were 10 people and we had total control of the match. I don't buy cheap talks that our players were so tired as Conte gave them proper rotation so far. Only Gagliardini and Bastoni had some games in a row but as far as remember the first one was subbed against Brescia and the latter had rested against Parma. With one extra man on the pitch, we could have easily control the game and make Bologna players "died" from chasing the ball. So, this complaint of yours that was so hot and our players were so tired and Bologna's were so fresh because of subs ( 38 years old Placio lol), reminds me of Mazzari's complaining about the rain.
It was more like our second half against Barca away or second half against Borussia away. For some reason, we stop playing our football and only watching how the opponent takes over control of the game without any resistance. It's not for the first time and most probably won't be for last. Conte's job is to resolve this.
