Atalanta became the first Serie A team to score four times in the opening 15 minutes of a match since 1932 in a thrashing of Bologna.
Gian Piero Gasperini's side moved to within a point of AC Milan in the final Champions League qualification place after demolishing Bologna at Atleti Azzurri d'Italia on Thursday.
They struck twice in the first five minutes of the game, Josip Ilicic beating goalkeeper Lukasz Skorupski from outside the penalty area and scoring again just 122 seconds later.
Ilicic then turned provider as the hosts made it 3-0 in the ninth minute, setting up Hans Hateboer for a right-footed finish that continued Atalanta's dominance.
