Chelsea’s ownership under BlueCo, led by Todd Boehly and Behdad Eghbali, has transformed Stamford Bridge into one of football’s busiest transfer destinations. Since taking control of the club in 2022, the ownership group has invested an estimated £1.9 billion (€2.2bn/$2.5bn) in rebuilding the squad through an aggressive recruitment strategy focused on elite stars and emerging talents.
While the project has produced success stories such as Cole Palmer, Moisés Caicedo, Enzo Fernández and several promising youngsters, it has also resulted in a number of expensive transfer decisions that failed to deliver the expected impact.
The latest name to attract criticism is Alejandro Garnacho, whose difficult first season at Chelsea has reportedly placed him on the transfer list only one year after arriving from Manchester United.
His situation has reignited debate over some of the club’s most disappointing signings since BlueCo assumed control.
10. Carney Chukwuemeka (£20 million from Aston Villa, 2022)
Chelsea beat several Premier League clubs to sign highly rated midfielder Carney Chukwuemeka after his impressive performances for Aston Villa and England’s Under-19 European Championship-winning team.
The midfielder was considered one of England’s brightest prospects, but injuries and fierce competition limited his opportunities.
Across two and a half seasons, Chukwuemeka struggled to establish himself, making just 32 appearances before eventually moving to Borussia Dortmund after an initial loan spell.
9. Christopher Nkunku (£52 million from RB Leipzig, 2023)
Chelsea believed they had secured one of Europe’s finest attacking players when they completed the signing of Christopher Nkunku.
The French international had been outstanding for RB Leipzig, winning the Bundesliga Player of the Season award and consistently delivering goals and assists.
However, a serious knee injury suffered during pre-season disrupted his debut campaign.
Although he returned to action, he never regained his best form, while Cole Palmer emerged as Chelsea’s primary attacking star.
After limited Premier League appearances, Nkunku eventually completed a move to AC Milan.
8. Alejandro Garnacho (£40 million from Manchester United, 2025)
Chelsea’s decision to sign Alejandro Garnacho surprised many observers after the Argentine winger fell out of favour at Manchester United.
Despite his reputation as one of South America’s brightest young talents, Garnacho struggled to reproduce the explosive performances that made him a fan favourite at Old Trafford.
Reports suggest Chelsea are already prepared to sell the winger after only one season, hoping to recover between £43 million and £45 million, although attracting buyers at that valuation may prove difficult.
7. Pierre Emerick Aubameyang (£10.3 million from Barcelona, 2022)
Chelsea signed the experienced striker following a successful spell at Barcelona, largely because then-manager Thomas Tuchel wanted to reunite with his former Borussia Dortmund forward.
Just days after Aubameyang arrived, Tuchel was dismissed.
Without the manager who requested his signing, the Gabon international struggled for opportunities under Graham Potter, scoring only three goals before leaving on a free transfer.
6. Kalidou Koulibaly (£33 million from Napoli, 2022)
After years of dominating Serie A with Napoli, Kalidou Koulibaly was expected to become Chelsea’s new defensive leader following Antonio Rudiger’s departure.
Instead, the Senegal captain struggled to adapt to the pace and intensity of English football.
After only one season, Chelsea accepted offers from Saudi Arabian club Al Hilal, ending a disappointing spell at Stamford Bridge.
5. Raheem Sterling (£47.5 million from Manchester City, 2022)
Sterling arrived as one of the Premier League’s most decorated attackers after winning multiple league titles with Manchester City.
Chelsea expected the England international to provide leadership, goals and experience.
Instead, inconsistent performances and changing managerial philosophies limited his impact.
Following an unsuccessful loan spell at Arsenal, Sterling eventually left Chelsea after the club terminated his contract in early 2026.
4. João Félix (£46 million permanent move after initial loan)
Chelsea pursued João Félix on two separate occasions.
His first spell came on loan from Atlético Madrid in 2023, but despite moments of quality, he failed to justify a permanent transfer.
The club nevertheless signed him again in 2024 following his encouraging season at Barcelona.
His second spell proved equally disappointing before he was loaned to AC Milan and later sold permanently to Al Nassr.
3. Facundo Buonanotte (Loan from Brighton, 2025)
Chelsea hoped Argentine playmaker Facundo Buonanotte would provide additional creativity during the 2025 campaign.
However, the loan never developed as expected.
The youngster featured only eight times across all competitions before the agreement was terminated midway through the season.
His short stay is remembered as one of Chelsea’s least effective recruitment decisions.
2. Deivid Washington (£17 million from Santos, 2023)
Brazilian striker Deivid Washington joined Chelsea as one of South America’s most exciting teenage talents.
Signed from Santos on a long-term contract, expectations were high that he would gradually develop into a first-team striker.
Instead, he made only three senior appearances while spending most of his time with the development squad and on loan.
Chelsea are now expected to sanction his permanent departure.
1. Mykhailo Mudryk (£89 million from Shakhtar Donetsk, 2023)
No player better represents Chelsea’s transfer frustrations than Mykhailo Mudryk.
The Ukrainian winger arrived after an intense transfer battle with Arsenal, with Chelsea agreeing a deal worth up to £89 million.
Initially viewed as one of Europe’s most exciting young wingers because of his explosive pace and technical ability, Mudryk struggled to adapt to Premier League football.
His Chelsea career suffered an even greater setback after receiving a four-year suspension for an anti-doping violation in 2026, leaving serious doubts over whether he will ever play for the club again.
The case transformed what was already considered an underwhelming transfer into one of the most expensive disappointments in Chelsea’s history.
A Project Still Under Scrutiny
Despite winning silverware and producing outstanding young talents, Chelsea’s transfer policy continues to divide opinion.
BlueCo’s willingness to invest heavily in youth remains central to its long-term strategy, but several costly mistakes demonstrate the risks associated with rapid squad rebuilding.
As another transfer window unfolds, Chelsea supporters will hope future signings resemble the success of Cole Palmer rather than the expensive disappointments that continue to define part of the BlueCo era.
