Atalanta pushed Bologna back for most of the match, but were unable to get the breakthrough in this goalless draw.
It was a surprising result, above all because the Rossoblu had been leaking goals in Serie A and the Coppa Italia, conceding seven in two games.
Riccardo Orsolini wasted an early opportunity for the visitors, while Robin Gosens and Ruslan Malinovskyi came close, but Atalanta had 21 attempts on goal, just three of them on target.
