Enzo Maresca left Chelsea after a sharp breakdown in trust with the club’s hierarchy, driven by poor recent results, clashes over the medical/fitness protocols, and his interest in returning to Manchester City.

Quick Scoop: What Actually Happened

  • Chelsea and Maresca “mutually agreed” to part ways, but multiple reports make it clear the club effectively decided to move on after crisis talks.
  • His exit came despite on‑paper success: he had delivered a top‑four finish and European trophies before things unraveled in late 2025.

Results On The Pitch

  • A poor run of form was a key trigger: Chelsea had just one win in seven Premier League games and repeatedly dropped points from winning positions.
  • The hierarchy felt performances were trending down rather than building on the previous season, which weakened Maresca’s position going into December.

Clash Over Injuries And Control

  • Maresca strongly disagreed with Chelsea’s independent medical department about when players should return from injury and how many minutes they could play.
  • Chelsea’s model gives the medical team the final say, but Maresca wanted more authority on selection and fitness, creating serious internal tension.

Breakdown With The Board

  • Reports describe a “breakdown in relations” between Maresca and the club’s leadership, with frustration at his increasingly public dissent and cryptic comments about internal issues.
  • His remark that he had just experienced the “worst 48 hours” of his Chelsea career, without explaining why, worried senior figures and deepened the disconnect.

Manchester City Factor

  • Maresca held talks with Manchester City about potentially succeeding Pep Guardiola, and he informed Chelsea as required in his contract.
  • Inside the club there was a feeling he had become distracted by the prospect of a return to City, which further eroded confidence that he was fully committed to the project.

In short: why did Maresca leave Chelsea? Because a bad run of results, open clashes over medical and sporting control, and his interest in Manchester City combined to shatter the working relationship, leading both sides to conclude a split was the only way forward.
