Atalanta dominated the first half, but Sampdoria won 1-0 against 10 men with Shkodran Mustafi’s controversial goal.
The Blucerchiati finally earned their first win of the season last week, upsetting Livorno in stoppages, but put Birkir Bjarnason as trequartista and Angelo Palombo in his old midfield role. Atalanta had won three on the bounce, but missed Giacomo Bonaventura, Stefano Lucchini, Giulio Migliaccio and Luigi Giorgi, so Franco Brienza and Mario Yepes stepped in.
This fixture last ended in a draw back in 1988-89, followed by 10 home wins and five away between Serie A and B.
Maxi Moralez arrived unbalanced to reach a Cristian Raimondi cross from nine yards and could only bundle it into the arms of the goalkeeper.
Atalanta lost Giampaolo Bellini early on to injury, so gave 20-year-old Constantin Nica only his second Serie A appearance.
German Denis dribbled in from the left only to blast his finish off target, then Denis knocked it down for Moralez and the ball carried on for Raimondi, who fired over from a tight angle under pressure.
Raimondi has only ever scored one Serie A goal in his career, but he came incredibly close to a second on the stroke of half-time. He got in front of his marker and aimed a looping header over Junior Da Costa only for it to smack the crossbar.
Sampdoria were utterly uninspired and jeered off the field by their own fans at half-time, so Delio Rossi introduced Savvos Gentsoglu in place of Palombo in midfield.
Rossi’s team talk had an effect, as within 55 seconds Manolo Gabbiadini had volleyed just past the near post. Gabbiadini grew up in the Atalanta youth academy.
Samp were transformed and Andrea Consigli smothered an Eder daisy-cutter. However, Atalanta were dangerous on the break and Andrea Costa charged down a Moralez attempt in the box with his chest after Raimondi had rolled across.
Consigli needed a fantastic save with his legs to deny Pedro Obiang, who had gone clear on goal from a smart Eder through ball.
The Blucerchiati took a deserved lead in absolutely chaotic circumstances. A corner found Shkodran Mustafi’s looping header and Luca Cigarini tried – and failed – to palm it off the line. At first the referee had shown a red card to Cigarini and awarded a penalty, but after discussion with his assistants ruled the ball was already over the line. Therefore Cigarini stayed on the pitch and Mustafi was given his goal.
Guglielmo Stendardo’s volley was charged down from a corner, but Atalanta did go down to 10 men eventually with substitute Nica shown a straight red card for going through the back of Eder.
Sampdoria nearly made it 2-0 moments later, as Consigli beat away Eder’s strike and Stendardo desperately scooped the loose ball clear. Denis had the chance to draw 10-man Atalanta level in the final minute, but he volleyed wide from a corner and Sampdoria got their first home win of the season.
