0-0! Milan scored 33 shots but did not score a goal, and although Milan played at home to Bologna, they never had a way to break the opponent's defense. Coach Pioli's substitution for this game was also questioned by fans.

High school striker Giroud started the game, is it time to play the cross to send the ball to Giroud? Unexpectedly, Milan played a pass control from the beginning, leaving Giroud, a high school striker, with no room to play. Giroud was replaced by Ibrahimovic in the 70th minute of the match, and then Ibrahimovic was injured in the collision with Medel, at which point Milan played a cross from the side, can it still be effective at this time?
In addition to tactical issues, Bennacer, who started the game, performed very well, not only sending a number of key passes, but also being very proactive in intercepting and confrontation in midfield. But in the 70th minute of the game, Pioli replaced Bennacer with Casey. Post-match statistics show that Bennacer contributed 2 shots, 3 key passes and 3 passes in the 70 minutes of the game, and contributed 5 steals and 1 interception on the defensive end.
Díaz, who was not in good shape, played the whole game on the field. If Pioli had not replaced Bennacer in this game, but replaced Díaz, I wonder if the result of this game would have been different? Fans said that Pioli dropped the chain at a critical moment, and the substitution of this game is debatable.
