Dries Mertens celebrating with his team-mates on the touchline after his decisive goal in the 4-2 victory at Sampdoria is typical of the spirit and togetherness that has seen Napoli storm to the top of the Serie A title. He has transformed the entire dynamics of how Napoli play, with clinical attacking movement combined with a rock-solid defence within a 4-3-3 system that is getting the very best from the players at his disposal. This seasona s statistics proved that point; Napoli are far and away the highest scorers in Serie A this season, while only Inter Milan and Juventus have a better defensive record. Napoli will need Higuain to carry his rich vein of form throughout the rest of the season if they are to have any chance of maintaining their wonderful pace and sprint clear of the chasing pack. Can Napoli maintain the pace?
