Chelsea ended the summer transfer window of 2026 as the most lucrative trading window in the club’s history. The Blues made around £415m from player sales alone, beating the £314m record they set 12 months ago, while spending £342m on signings, resulting in a net profit of £73m.
The team had to recalibrate after a chastening 2025-26 campaign. Chelsea finished the Premier League season in tenth place and then appointed Xabi Alonso to a four-year deal before the start of the campaign. The Spaniard inherited a squad without European football for the 2026-27 campaign and a bloated roster in need of severe pruning.
The final tone was set by two transactions. Aston Villa’s Morgan Rogers for £117m to become the most expensive British player of all-time. Manchester City agreed a £125m fee for Enzo Fernandez, which equals the British record set by Alexander Isak.
Here are all signings and departures assessed below.
Morgan Rogers – 8/10
The 24-year-old signed a £117m seven-year deal, eclipsing the £116m Manchester City paid for Elliot Anderson. Chelsea moved in after Arsenal continually turned down the chance to meet Villa’s valuation. On his debut at Craven Cottage, Rogers scored. He also assisted Pedro Neto against Brighton.
Maxence Lacroix – 7.5/10
The France international arrives from Crystal Palace for £52m on a contract that runs to 2032 and comes with two seasons of Premier League experience under his belt. Chelsea identified a glaring deficiency in experienced central defence, and Lacroix fills that need without foreclosing resale value at 26.
Marco Palestra – 7/10
Palestra came in for £47m from Atalanta after a loan stint at Cagliari, where he was voted Serie A’s best defender. The 21-year-old has committed his future to the club until 2033, but injury has postponed his English football debut.
Geovany Quenda – 7.5/10
The £43m move from Sporting was agreed in March 2025 and eventually completed this summer. The Portuguese teenager made 86 appearances and scored nine goals in Lisbon. His ability to play on the wing or as a right wing-back gives Alonso considerable tactical freedom.
Valentin Barco – 6.5/10
The £34m signing from Strasbourg sees the Argentine return to the Premier League after playing for Brighton and has been converted from left-back to a midfielder. He is contracted to 2033, but the positional ambiguity leaves room for genuine scepticism over the fee.
Emmanuel Emegha – 6/10
The Strasbourg skipper made the £22m move in a pre-agreed deal done in September 2025, after an injury-plagued campaign which saw him make just four Ligue 1 starts and score four goals. The Netherlands international has a big task on his hands to dislodge Joao Pedro.
Pep Chavarria – 6/10
The 28-year-old has penned a deal until 2031 after four seasons in La Liga with Rayo Vallecano, who Chelsea have paid £16.3m plus add-ons. He is a useful rather than a glittering replacement, and the modest outlay reduces the risk.
Emiliano Martínez – 8/10
Chelsea have moved for Martinez after being unconvinced by Robert Sanchez, with the World Cup winner arriving from Aston Villa on a three-year contract for just £7.5m. Martinez made his debut against Brighton, and the price is good value for a custodian of his pedigree.
Danny Welbeck – 6.5/10
Chelsea signed the 35-year-old from Brighton for £5m on a two-year deal, believing he could bring the sort of seniority that was so glaringly absent from the squad. Now in his 19th season in the Premier League, he is as much an adviser as he is a scorer.
Dastan Satpaev – 7/10
The £3.3m deal from Kairat was agreed in February 2025 but formalised as he turned 18, and the Kazakhstan international scored six minutes into his pre-season debut. He has since joined up with Burnley on loan to get a feel for English football.
Jordan Henderson – 6/10
Chelsea missed out on Granit Xhaka and brought in the former Liverpool captain on a free transfer from Brentford, handing the 36-year-old a two-year contract. This signing is purely about leadership and dressing-room control, not about any remaining physical capacity.
Enzo Fernandez – 9/10
Chelsea will make an £18m profit on the Argentine, whom they signed from Benfica for £107m three and a half years ago. He had been insistent that he wanted out, so this was a hugely profitable way of solving an impossible situation.
Andrey Santos – 7/10
The midfielder played 47 games for Chelsea, scoring 3 goals. Manchester United paid £48m, with a potential to rise to £50m. The risk of selling a homegrown asset after only one season with the first team is obvious, but the financial upside is significant.
Nicolas Jackson – 8/10
The Senegal international rejoined Unai Emery at Aston Villa for an initial £47.5m that could rise to £65m with add-ons. Chelsea recouped a hefty fee for a striker whose departure had been long overdue.
Marc Cucurella – 6/10
Real Madrid paid £47.5m plus £4.3m in add-ons for a defender who made 163 appearances and won the Conference League and Club World Cup. The sale was perceived as a blow to Alonso, who was already short of experienced personnel.
Liam Delap – 8/10
The 23-year-old became Nottingham Forest’s record signing at £50m, only a year after arriving at Stamford Bridge. Shrewd business by BlueCo in getting back the full outlay after a disappointing debut campaign.
Trevoh Chalobah – 5/10
The academy graduate has joined Como in a £25.7m deal after making 47 appearances last season, ending an almost two-decade association. The most contentious call of the window will be to sanction the exit of a dependable, homegrown centre-back amid a wider exodus of centre-backs.
Tyrique George – 6/10
Everton had an option to buy him at £25m after his loan spell, but the two clubs agreed a compromise fee of £18m, which could eventually rise to £24m. The 20-year-old made only 11 appearances on Merseyside before signing a four-year deal at the club.
Marc Guiu – 7/10
The 20-year-old, who made 11 Premier League appearances without finding the net, has signed a five-year deal with RB Leipzig for £13.7m. To realise that sum for an unproductive squad forward is an unequivocally satisfactory result.
Tosin Adarabioyo – 6.5/10
The defender joined on a free transfer from Fulham in 2024 before Tottenham activated a £7m fixed fee plus add-ons deal. He has been absent from Chelsea’s matchday squad for the opening three games of the season.
Mykhailo Mudryk – 8/10
Tottenham saw the Ukrainian play no competitive football for 20 months before he was cleared in July, but they secured a season-long loan with an option to buy for £75m. That clause, and the possibility of recouping the initial investment, is quite the good business.
Benoît Badiashile – 7/10
Napoli have agreed a season-long loan deal with an option to buy for around £17m. They will pay around £2.6m for the privilege, but the Frenchman managed only 16 appearances last term. Moving a peripheral defender with a defined exit route is good squad management.
Axel Disasi – 6/10
The France international has moved to Crystal Palace on another loan after temporary spells at Aston Villa and West Ham United, and the club will have a large wage bill on their books for another season.
Robert Sanchez – 7/10
Como signed the Spaniard on loan on deadline day, with the option to buy him at the end of the season. His mistakes in the win over Fulham effectively ended his Chelsea career.
Mamadou Sarr – 7/10
The 20-year-old defender spent half of last season back at Strasbourg before being reintegrated in January, but has now joined Real Sociedad on loan. Getting competitive minutes in La Liga is a perfectly logical step in development.
Filip Jørgensen – 7/10
The Denmark international has moved to Strasbourg for the season after failing to establish himself as first choice, effectively swapping places with Mike Penders. The Martinez signing made his departure not just likely but practically inevitable.
Dario Essugo – 5/10
Hull City had been close to signing the Portuguese midfielder, but the deal collapsed, and he has instead joined Strasbourg on a season-long loan. His departure, coupled with the Fernandez sale, leaves Chelsea with only five senior midfielders for the campaign.
Alejandro Garnacho -6/10
The Argentine scored one goal in 24 Premier League games and has joined Aston Villa on loan, with the move to become permanent if certain conditions are met.
David Datro Fofana – 6/10
After five loan spells and just three league appearances for Chelsea, the Ivorian has finally found a permanent exit, moving to Servette for £2.1m. The resolution is long overdue, and the recovered fee is largely incidental.
Caleb Wiley – 6/10
The American full-back has dropped down to the Championship with Preston North End after spending last season on loan at Watford. He has yet to play competitively for Chelsea, and the prospect of that happening looks increasingly remote.
Overall window score for Chelsea – 7.5/10
Alonso’s main issue will be the absence of a central midfielder. Chelsea agreed the Fernandez fee without a replacement lined up, saw two bids for Lamine Camara rejected, and held talks over Manu Kone. However, they’ve signed quality in attack and between the sticks, while selling a number of players that weren’t needed. The first big test for the squad Alonso has assembled will come when they travel to face champions Arsenal on September 6.
