Dries Mertens scored his first goal in 910 minutes of league football as Napoli beat Atalanta 1-0 away from home.
Dries Mertens scored his first league goal since October as Napoli maintained their Serie A title challenge thanks to a 1-0 win at Atalanta.
Maurizio Sarri's men went into the game a point ahead of second-placed Juventus - who host Genoa on Monday - having won their last four in the league and, although it was by no means a comfortable outing, Mertens made the difference in the second half.
The first period passed with little excitement, as the two sides generally cancelled each other out in midfield and neither managed to get a shot on target.
