Atalanta, last year’s top-scorer with 98 goals, had netted 13 while winning its first three games this season, but had no answer to Napoli’s attacks in an extraordinary first half. Hirving Lozano, out of favour with manager Gennaro Gattuso last season, set Napoli on its way with two goals in four minutes.
The Mexican forward tapped in from Giovanni Di Lorenzo’s cross in the 23rd minute and curled in the second goal after Dries Mertens pounced on a mix-up in the Atalanta midfield. Matteo Politano fired the third goal on the half hour and Nigeria forward Victor Osimhen took advantage of more poor defending to score the fourth before the interval.
Napoli goalkeeper David Ospina’s kick was misjudged by Cristian Romero and Osimhen, signed from Lille in the summer, chested the ball down and scored with a shot on the turn to net his first goal for his new club.
Romero partially made amends by setting up Atalanta’s consolation goal for substitute Sam Lammers in the 69th minute. The Argentine won possession, charged upfield and released Lammers, who clipped his shot past Ospina.
RESULT: Serie A: Napoli 4 beat Atalanta 1. La Liga: Granada 1 beat Sevilla 0; Celta Vigo 0 lost to Atletico Madrid 2.
