Since Roman Abramovich acquired Chelsea in 2003, the club has undergone significant transformations in the transfer market. While some acquisitions have brought glory, others have fallen short, leaving a trail of disappointment and financial burden. Here, we delve into Chelsea's ten worst signings in recent history.

10. Romelu Lukaku

Romelu Lukaku's return to Chelsea in 2021 for a club-record fee was met with high expectations. However, his second stint at Stamford Bridge was marred by underperformance and public criticism of manager Thomas Tuchel's tactics. Lukaku's departure on loan to Inter Milan and subsequently to AS Roma solidifies his status as one of Chelsea's biggest transfer flops.

9. Kepa Arrizabalaga

Chelsea's decision to break the world-record fee for a goalkeeper with Kepa Arrizabalaga's signing from Athletic Bilbao failed to yield desired results. Despite promising performances under Maurizio Sarri, Kepa's form plummeted, leading to his relegation to the bench and eventual loan move to Real Madrid.

8. Tiemoue Bakayoko

Tiemoue Bakayoko arrived at Chelsea with high expectations following his success at AS Monaco. However, his tenure at the club was marred by inconsistent performances and disciplinary issues, leading to multiple loan spells before his eventual departure to Ligue 1 side Lorient.

7. Michy Batshuayi

Michy Batshuayi's arrival from Marseille was heralded as Chelsea's solution to their striking woes. However, the Belgian forward failed to replicate his Ligue 1 form in the Premier League, resulting in loan spells and a permanent transfer to Fenerbahce after a disappointing spell at Stamford Bridge.

6. Danny Drinkwater

Chelsea's acquisition of Danny Drinkwater in 2017 raised eyebrows, with the midfielder failing to justify his hefty price tag. Despite limited opportunities, Drinkwater struggled to make an impact, leading to loan moves and eventual release from the club.

5. Alvaro Morata

Alvaro Morata's arrival from Real Madrid was met with anticipation, but the striker failed to live up to expectations. Inconsistent performances and poor finishing saw Morata loaned out before a permanent move to Atletico Madrid, marking a disappointing chapter in Chelsea's transfer history.

4. Adrian Mutu

Adrian Mutu's signing from Parma promised much but delivered little for Chelsea. Despite an initial flurry of goals, Mutu's career at the club was marred by off-field issues, culminating in a ban for cocaine use and a legal battle with the club, resulting in his departure under contentious circumstances.

3. Andriy Shevchenko

Andriy Shevchenko's arrival from AC Milan was met with great fanfare, but the Ukrainian striker failed to replicate his Serie A form in the Premier League. Despite moments of brilliance, Shevchenko's stint at Chelsea was marred by inconsistency, leading to a loan return to Milan before departing for Dynamo Kyiv.

2. Fernando Torres

Fernando Torres's arrival from Liverpool as Chelsea's record signing brought high expectations, but the striker struggled to recapture his Anfield form. Despite memorable moments, Torres failed to justify his price tag, ultimately falling short of Chelsea's lofty ambitions.

1. Juan Sebastian Veron

Juan Sebastian Veron's arrival from Manchester United failed to meet expectations, with the Argentine midfielder struggling to make an impact at Chelsea. Limited playing time and underwhelming performances saw Veron depart the club without fulfilling his potential.
