Sevilla, the Spanish Premier League club known for its defensive prowess, has been able to make strides in recent weeks by securing two consecutive clean sheets and reducing weaknesses in their defense. The team's performance is evident from the fact that they have not allowed a single goal this season.

The first consecutive clean sheet came on September 22nd when Sevilla defeated Real Madrid at home, scoring three goals in the process. This was followed by another impressive display against Athletic Bilbao on October 5th, where they secured a victory despite conceding a penalty kick late in the game. In both games, Sevilla's defense managed to keep a clean sheet without conceding any goals.

One of the key reasons behind Sevilla's success in defense is the combination of their experienced defenders and the tactical approach taken by coach Sergio Garcia. Garcia has a proven track record of creating space for his players to play and has implemented a system that allows them to move freely across the pitch while maintaining control of the ball. This approach has enabled the defense to maintain their high level of performance throughout the season.

In addition to the clean sheets, Sevilla has also reduced the number of weak areas in their defense. They have tightened up their backline and eliminated some of the weaker defenders who were often left open by opponents' attacks. This has resulted in improved defending and more consistent results on the field.

Overall, Sevilla's defense has shown significant improvement since last season, and it is likely that this will continue as the team continues to develop and improve over time. With the right mix of tactics and teamwork, the defense can continue to push Sevilla towards success in the upcoming seasons.
