Sevilla's defensive vulnerabilities have been highlighted by their recent performances, conceding eight goals in five matches. The club's defense has struggled to keep clean sheets, and this has led to concerns about the team's overall performance.

One of the most obvious issues with Sevilla's defense is their inability to deal with opponents' fast-paced attacking styles. The team has conceded goals at an alarming rate, and this has resulted in them being unable to maintain possession for long periods of time. This lack of control over the game has made it difficult for Sevilla to create any meaningful chances on goal.

Another issue that Sevilla's defense faces is the fact that they rely heavily on their midfielders to provide the ball out from the back. However, this reliance on the midfielders has led to the club's defense being exposed in one-on-one situations. This has resulted in the team conceding goals at a high rate, as opposition players have been able to exploit the gaps left behind by the midfielders.

Furthermore, Sevilla's defense has also suffered from injuries and suspensions, which has further added to their struggles. With key players like Gerard Pique and Juanmi unavailable due to injury or suspension, Sevilla's defense has been weakened even further.

Overall, Sevilla's defense has been a major concern for the team this season. They need to address these issues if they want to turn things around and compete for top honours.
