Enzo Maresca's First Month at Chelsea: Data-Driven Analysis of His Tactical Approach and Impact

Defensive High Line and High Pressing

Another important aspect of Maresca’s tactical philosophy is his commitment to a high defensive line and intense pressing when out of possession. The team has shown clear improvements in this regard, executing the high press effectively and forcing turnovers in dangerous areas. Data on high turnovers suggests Chelsea are among the more successful teams in this regard, reflecting the success of Maresca’s pressing system.

However, defensive issues still persist, particularly when CFC are forced into passive defensive phases, such as mid or low blocks. When sitting deeper, the side appears vulnerable, leaving space for opposition teams to exploit. This lack of coordination between the midfield and defensive lines is something Maresca must address in the coming weeks to solidify Chelsea’s defense.

Box Entry Efficiency and Finishing Concerns

Another area that requires attention is box entry efficiency. While Chelsea have been strong at progressing the ball into the final third, they have struggled to consistently penetrate the opposition’s penalty area.

This inefficiency is compounded by underwhelming shot conversion rates, which have prevented CFC from capitalizing on the chances they create. Improving both of these aspects will be crucial for Blues success in the long term.

Final Thoughts

The tactical blueprint Maresca is laying down at Chelsea appears to be a departure from his previous approach at Leicester City. He is keen on varying his team’s attacking approach, blending direct attacks with patient possession-based build-ups. CFC are excelling in certain areas—pressing high, forcing turnovers, and progressing the ball - but also have significant room for improvement, especially in defensive phases and box penetration.

In conclusion, Chelsea under Maresca is a work in progress. While the team has shown promise in certain areas, they still face challenges that need addressing. As the season unfolds, we will be monitoring closely to see if the Blues can iron out their deficiencies and continue their upward trajectory under Maresca’s guidance. If these issues are addressed, his team have the potential to become one of the more tactically astute teams in the league.
