Gasperini believes the draw against Rossoblu at the Stadio Renato Dall'Ara was a bad result and has slammed his men for being complacent.
Atalanta’s bright start to the game was rewarded with two quick goals in the 22nd and 23rd minutes respectively, with both coming from Colombia striker Luis Muriel.
La Dea passed up many chances to put the game to bed even before the interval and allowed Bologna to mount a comeback.
Takehiro Tomiyasu got one back for the hosts inside 73 minutes before Nehuen Paz pulled parity eight minutes before the final whistle.
“It’s a bad result for us,” Gasperini told Sky Sport.
“We were dominating the game, but they are comeback specialists. We had many goal-scoring chances and it’s hard to explain what happens. We have thrown two points away. Being presumptuous is not something we can afford. It would be very bad to be presumptuous and arrogant,” the Italian coach added.
Atalanta had an amazing year as they reached the Champions League quarter-final in their debut campaign.
Gasperini admitted it was an amazing year for the Bergamo-based club but insists the Coronavirus pandemic took the joy out.
“It was an extraordinary year, but the pandemic takes away the joy of the results on the field,” said Gasperini.
