Atalanta beat Fiorentina (1-0), on Sunday, in a game that brought them back to the top of Serie A, with the same points as Napoli which previously won 3-1 home against Torino.
After a goalless first half, Gasperini's team managed to take the lead close to the hour of play, through a goal by Lookman, after Muriel's pass.
The visiting team still tried to equalize and had a few chances to do so, but the truth is that the scoreboard did not move again.
With this result, Atalanta now has the same 20 points as Napoli at the top of Serie A, while Fiorentina is ninth with 11 points.
