Napoli are showing signs of life. A convincing 3-0 win over Frosinone at the Maradona on Saturday gave Massimiliano Allegri's side a much-needed boost after a difficult start to the season, and the manner of the victory was as encouraging as the result itself. Kevin De Bruyne was the standout performer, scoring twice and controlling the game from a central role that, by his own admission, is not his preferred position. His display was the clearest sign yet that Allegri's decision to switch to a back three is beginning to pay off, with president Aurelio De Laurentiis publicly praising the tactical shift. Noa Lang also impressed, and the returning Scott McTominay came off the bench to a warm reception from the home crowd after missing over a month with a cardiac arrhythmia issue. His comeback adds genuine depth to a midfield that has been stretched by a long injury list including Buongiorno, Olivera, Anguissa and Vergara. The win lifted Napoli to eighth in Serie A with 10 points from six games, level with Frosinone in ninth and just behind Como in seventh. The squad now turns its attention to Europe, with a Champions League away fixture against Villarreal on Tuesday. Napoli lost their opening group game to Arsenal, making Tuesday's match in Spain a significant test of whether this week's momentum can carry into continental competition.
