Bologna -Vleugel player Riccardo Orolini scored in extra time to achieve a memorable victory over the current Serie A champions.
The defeat of Inter has opened the door for Napoli from Antonio Conte with both parties now on points at the top of the table with 71 from their 33 games.
After the game spoken to the press, Inzaghi points to a certain decision that believes that he cost his side.
“There was tension over the latter intervention, which was brought forward 12-13 meters further from the original position,” Inzaghi told Dazn.
“That is just an objective fact. Having said that, we could still have dealt better with the situation, because two of us started to jump and it should always be one.”
Referee Andrea Colombo sent Bologna -coach Vincenzo Italiano and Inzaghi's Assistant -Massimiliano Farris for two separate touchline incidents during the game.
