Since Roman Abramovich took over Chelsea Football Club in 2003, the West London side has become one of the most fruitful clubs in Europe. Known for its ruthless sacking culture, Chelsea has also witnessed some of the most compelling directors in football. Here are the top 15 Chelsea managers from the Abramovich period (2003) to 2025, ranked based on their impact, trophies, and legacy.

1. José Mourinho (2004–2007, 2013–2015)
The “Special One” revolutionised Chelsea. He won 3 Premier League titles, 1 FA Cup, and 3 League Cups across two spells. Mourinho built a prevailing squad and set up a winning mentality.

2. Thomas Tuchel (2021–2022)
Tuchel arrived mid-season in 2021 and instantly won the UEFA Champions League, UEFA Super Cup, and FIFA Club World Cup. His strategic brilliance brought stability and silverware.

3. Carlo Ancelotti (2009–2011)
Ancelotti conveyed Chelsea’s first-ever Premier League and FA Cup Double in 2009–10, playing attractive, attacking football. His team scored a then-record 103 league goals.

4. Antonio Conte (2016–2018)
Conte transformed Chelsea with a 3-4-3 system, winning the Premier League in 2016–17 and the FA Cup in 2018. His intense style re-energised the squad.

5. Roberto Di Matteo (2012)
Di Matteo may have had a brief spell, but he has driven Chelsea to their to begin with UEFA Champions League title and an FA Cup, making him a club legend forever.

6. Guus Hiddink (2009 & 2015–16)
In times meantime, Hiddink won the FA Cup in 2009 and made a difference in stabilising the group during his momentary stretch. Beloved by fans for his calm approach.

7. Mauricio Pochettino (2023–2024)
Although trophyless, Pochettino brought a youthful squad to the League Cup final and came to Europe once more, laying the foundation for long-term improvement before his 2024 departure.

8. Frank Lampard (2019–2021, 2023)
A club legend, Lampard guided Chelsea to the top 4 with a transfer ban, using academy talents. His return as interim in 2023 wasn’t as successful, but sincerely significant.

9. Luiz Felipe Scolari (2008–2009)
Scolari began brightly but misplaced force and was sacked mid-season. His time was brief but marked by some appealing football.

10. Rafael Benítez (2012–2013)
An unpopular appointment, Benítez still delivered the UEFA Europa League and a top-three wrap-up. A success in hindsight.

11. Andre Villas-Boas (2011–2012)
As seen in the following, Mourinho, Villas-Boas battled to handle enormous egos and were sacked within a year. His extend was also short-lived.

12. Graham Potter (2022–2023)
A strong appointment from Brighton, but results plunged quickly. Despite a poor run, Potter introduced several key players presently significant to the squad.

13. Avram Grant (2007–2008)
He took Chelsea to the Champions League last and finished 2nd in the league. Strong, if unspectacular.

14. Claudio Ranieri (2000–2004)
Though pre-Abramovich for most of his residency, Ranieri made a difference in constructing the squad Abramovich acquired. A foundation layer for future success.

15. Bruno Saltor & Intervals Staff (Various)
Multiple inside players like Steve Holland, Bruno Saltor, and others made a difference to Chelsea through their moves. Their parts were small but crucial amid turbulence.

Conclusion
Chelsea’s administrative history since Abramovich has been sensational and ever-changing. Whereas a few were sacked as well early, others had periods of dominance. Despite the turnover, these 15 supervisors moulded Chelsea into one of Europe’s top football clubs by 2025.
