In the world of football, there is no more pressing issue than maintaining the defense's ability to shut down opposing offenses and prevent them from scoring goals. The Chelsea team has shown remarkable resilience throughout the season, but they have struggled with defending 8 goals per game while conceding just one goal per match.

One of the reasons why Chelsea has struggled so much defensively is due to their lack of creativity on the ball. Despite having a talented squad at their disposal, they struggle to find the proper passing lanes that allow players to create chances. This has led to frequent mistakes, which can result in costly defeats.

Another factor contributing to Chelsea's defensive struggles is their tendency to play narrow sets of positions. As a result, they often find themselves caught offside or without enough space to attack the opposition's backline. This can lead to missed opportunities and ultimately result in conceding goals.

To address these issues, it is imperative that the Chelsea team takes immediate action. Firstly, they need to develop a clear plan for attacking plays and identify who will be in charge of each position. Secondly, they should work on improving their positioning, including changing formations and moving players around the pitch. Thirdly, they must focus on creating space between the defenders and midfielders by playing more forward passes.

In conclusion, the Chelsea team faces a significant challenge in maintaining their defensive record of only conceding one goal per match while scoring eight goals per game. By developing a clear plan for attacking plays, improving their positioning, and focusing on creating space, the Chelsea team can improve its defensive performance significantly. With these measures taken, the Chelsea team stands a good chance of achieving their goal of staying undefeated in the Premier League this season.
