Sevilla's defensive weaknesses have been a major concern for the team this season, as they have struggled to keep their opponents at bay. One of the main issues is that the defense lacks stability, with inconsistent performances from key players such as Jules Kounde and Antonio Rüdiger.

Another issue is that Sevilla has struggled to find consistent ball possession, which can be exploited by opposing teams. This lack of control over the game can leave the defense exposed, making it difficult to defend against counterattacks.

The other weakness is the inability of the backline to communicate effectively. When defenders do not understand each other's roles or positions on the pitch, it can lead to errors in marking and positioning, which can result in goals.

Overall, Sevilla's defensive shortcomings have hindered their performance this season and will need to be addressed if they want to compete at the highest level. The team needs to focus on improving communication between its defenders and developing a more cohesive defensive unit.
