Romelu Lukaku and Danilo D'Ambrosio's second-half goals got Inter Milan back winning 2-0 at Genoa on Saturday to move third in Serie A ahead of Atalanta who fell 3-1 to Sampdoria.
Antonio Conte's Inter bounced back after a 2-1 derby defeat to AC Milan and a 2-2 Champions League stalemate at home against Borussia Moenchengladbach.
After being pegged back in the first half, Conte brought reinforcements off the bench with Nicolo Barella coming on for Christian Eriksen and Achraf Hakimi replacing Ivan Perisic, just hours after the Moroccan defender tested negative for coronavirus.
Barella set up Lukaku to open the scoring after 64 minutes, his fifth league goal this season. D'Ambrosio nodded in the second with ten minutes to go.
Inter move up to third, two points behind leaders AC Milan, who host Roma on Monday, and one-point ahead of Atalanta, fourth after a second straight defeat.
Atalanta are level on points with Claudio Ranieri's Sampdoria who followed up wins over Fiorentina and Lazio.
"Last year we were in a full battle to avoid relegation and it was difficult to challenge Atalanta," said Ranieri.
"I told the lads I wanted to see courage against Lazio and Atalanta. We gradually gained confidence and were ready when the opportunities came."
Fabio Quagliarella opened the scoring after a quarter of an hour with his fourth goal in as many games, but the veteran striker was denied a second from the penalty spot.
Danish midfielder Morten Thorsby added a second before the hour mark, with Jakub Jankto sealing the points in injury time.
Colombian striker Duvan Zapata pulled a goal back for Atalanta with 10 minutes to go from the penalty spot.
