Two goals from Arkadiusz Milik helped Napoli return to winning ways in Serie A with a 2-0 home victory over Hellas Verona on Saturday.
The Poland international had not scored this season going into the game, but struck in either half to end his drought.
Napoli's form stuttered before the international break as they were held to two consecutive goalless draws, against Torino in Serie A and Genk in the Champions League.
But a comfortable victory at the Stadio San Paolo helped Carlo Ancelotti's side close the gap on third-placed Atalanta to just one point after they were held to a draw by Lazio.
Napoli are fourth on 16 points, one behind Atalanta and four ahead of fifth-placed Roma, who face Sampdoria on Sunday.
