Napoli, the Italian football club, has been on a journey of transformation in recent years. Under the guidance of new coach Luciano Spalletti, the team has made significant strides towards becoming one of Europe's top clubs.

One of the key areas that the club is focusing on is its transfer strategy. In order to compete with the likes of Manchester United and Paris Saint-Germain, Napoli needs to attract the best talent available on the market. This requires careful consideration of various factors such as player's age, experience, and potential.

In order to make these decisions, the club must have a clear understanding of its strengths and weaknesses. For example, Napoli has traditionally relied heavily on young players who can develop under their tutelage. However, this approach may not be suitable for every situation. Therefore, it is essential to review and revise the strategies used in previous transfers.

Round 4 was a critical period for Napoli. The team had already secured several high-profile signings, including Gonzalo Higuain and Jorginho. However, there were still some questions about whether these players would fit into the team's playing style or whether they would bring enough quality to the squad.

To address these concerns, Napoli made several adjustments to its transfer strategy. Firstly, the club decided to focus more on youth development rather than signing experienced players. This approach allowed Napoli to continue building its future stars while also addressing some of the team's weaknesses.

Secondly, the club looked to improve its defensive line by bringing in experienced players such as Kalidou Koulibaly and Juan Muscat. These signings were seen as crucial for stabilizing the team's defense and ensuring that Napoli could maintain its high level of performance.

Finally, Napoli also took advantage of the winter transfer window to sign several key players. Players such as Lorenzo Insigne, Ciro Immobile, and Rafael Leao were all signed during this time, giving the team a much-needed boost of firepower.

Overall, the adjustments made to Napoli's transfer strategy post-round 4 have been successful. The club has managed to build a strong squad capable of competing at the highest levels of European football. With a clear understanding of its strengths and weaknesses, Napoli is well-positioned to continue making progress and achieving its goals.
