The Serie A season is in full swing, and Napoli has been one of the most exciting teams to watch so far. After four rounds, they sit second in the league table with six points from their games played.

One of the key players who has contributed significantly to Napoli's success this season is Lorenzo Insigne. The Italian striker has scored three goals in his first four appearances for the club, and he is playing at his best under new manager Maurizio Sarri.

Sarri, who previously managed Chelsea, is known for his tactical acumen and ability to adapt transfer strategies to suit his team's needs. He has done just that with Napoli, using a variety of tactics and formations to get the best out of his players.

Insigne himself has also adapted to the new system quickly. Under Sarri, he has become more assertive in front of goal, taking more shots and creating more opportunities for himself and his teammates.

Another player who has benefitted from Sarri's approach is star defender Kalidou Koulibaly. The Senegalese international has been a rock at the back for Napoli since joining the club last summer, and Sarri has helped him to improve even further.

Overall, it seems that Sarri's approach to coaching and adapting transfer strategies has paid off for Napoli. With their performances in recent weeks, they have established themselves as serious contenders for the title. As the season progresses, we will see how much they continue to improve under Sarri's guidance.
