La Dea started the game without their top scorer, Ademola Lookman, but still found a way to win without their Nigerian talisman, left as an unused substitute, thanks to another African striker, Jeremie Boga.
The Ivorian winger went into half-time with Atalanta trailing, but turned the tie around with two assists to inspire a 2-1 win.
Bologna 1-2 Atalanta
Atalanta were eager to get off to a positive start after dropping points to Spezia in midweek, but it was Bologna who drew first blood after just six minutes.
Riccardo Orsolini picked up the ball on the edge of the box and drove a powerful shot into the far corner to register his third goal of the season and give the hosts the lead.
Bologna headed into the half-time break with the lead as Atalanta failed to even register a shot on goal, but that would change in the second half.
Boga needed just two minutes to make his mark after going into halftime when he slotted the ball into the path of Teun Koopmeiners, who produced a sublime effort from long range, blasting his shot past the outstretched Lukasz Skorupski.
Boga went up again with a through ball to Rasmus Hojlund to score and complete Atalanta’s turnaround before the hour of play
Atalanta controlled the rest of the game to see the result that placed them in sixth position in the Serie A table.
