Chelsea's defense has been under scrutiny recently as the team has struggled to keep goals out of their net. In just five matches this season, Chelsea has conceded eight goals, which is one of the highest totals in the Premier League.

There are several reasons why Chelsea's defense may be struggling. One of the main issues is that the team has lacked consistency in their defensive play. The Blues have had some poor performances where they have allowed multiple goals and others where they have been solid throughout.

Another factor that could be contributing to Chelsea's defensive woes is the lack of depth in their squad. The team has only two full-backs and three center-backs, which can make it difficult for them to rotate players and rest bodies.

Additionally, the team's reliance on set-pieces and counter-attacks has put more pressure on their defense. When opponents take advantage of these opportunities, it can be difficult for Chelsea's defenders to cope with the pace and power of their attackers.

In conclusion, Chelsea's defense needs to be addressed if they want to compete at the top level of English football. The team needs to work on improving their defensive organization and creating a more cohesive unit. They also need to address the issue of depth in their squad and find ways to rest players who are playing too many games. With these changes, Chelsea's defense could become a strength rather than a weakness.
