The defensive impact at Paris Saint-Germain has been one of the most talked-about topics in the French league this season. The team, which was heavily criticized for its poor defense last year, has improved significantly under new coach Mauricio Pochettino.

One of the key players who have made a significant difference in the team's defensive performance is Thiago Silva. The Brazilian defender has played a vital role in the team's success, providing leadership and experience to the young defenders on the team.

Another player who has had a significant impact on the team's defensive performance is Marco Verratti. The Italian midfielder has worked tirelessly to improve his defensive skills, helping to provide cover for the back four and preventing counter-attacks.

In addition to these two players, the team has also benefited from the arrival of new signings such as Juan Bernat and Layvin Kurzawa. These players have added depth and quality to the team's defense, making it more difficult for opponents to break down their defenses.

Overall, the defensive improvements at PSG have been a major reason for the team's success this season. With the likes of Silva, Verratti, and the new arrivals contributing to the team's defensive strength, PSG is well-positioned to compete for titles in the coming seasons.
