Substitute Arkadiusz Milik scored five minutes from time and Napoli won 2-1 at Atalanta on Monday to keep alive its faint Serie A title hopes.
Second-placed Napoli moved back within eight points of seven-time defending champion Juventus; and three points ahead of third-placed Inter Milan.
Milik scored with an expert volley following a cross from Mario Rui three minutes after he came on for Dries Mertens.
Fabian Ruiz put Napoli ahead less than 90 seconds in by redirecting a splendid cross from Lorenzo Insigne on a counterattack.
Former Napoli forward Duvan Zapata equalized after the break from close range.
Atalanta remained 11th.
