AC Milan boss Sinisa Mihajlovic was disappointed that his side needed extra time to beat Serie B outfit Crotone in the Coppa Italia on Tuesday.
The Rossoneri booked a spot in the last-16 of the competition, but needed Giacomo Bonaventura and M'Baye Niang to score in added time after Ante Budimir had cancelled out Luiz Adriano's early strike in normal time.
"There are no easy victories as every match is played on the field," Mihajlovic told reporters after the game.
"I didn't expect to play extra time as I was convinced we would win. I wanted to keep the likes of [Carlos] Bacca and Niang on the bench but in the end I needed them.
"When Bonaventura, Niang and [Riccardo] Montolivo came on we improved in terms of quality. Some the players that started did well while others didn't, but that was to be expected as they rarely play.
"Along with that, Crotone showed they are a difficult team to play against and they had the backing of the many fans that came to San Siro."
