Chelsea have made a dramatic late move in the summer transfer window, agreeing a £7.5 million deal with Aston Villa for Argentina goalkeeper Emi Martinez as they look to strengthen a position that has suddenly become a major concern.
The 33-year-old is set to undergo a medical in London before completing his move to Stamford Bridge, where he will provide experienced competition for Robert Sanchez and add another high-profile option to Xabi Alonso’s squad.
The decision represents a remarkable change of direction for Chelsea, who had previously been prepared to continue backing Sanchez as their first-choice goalkeeper. However, concerns over his performances in the opening game of the Premier League season have accelerated the club’s search for an alternative.
Emi Martinez arrives after Chelsea goalkeeper concerns

The arrival of Emi Martinez follows a difficult opening-night performance from Sanchez during Chelsea’s 3-2 victory over Fulham at Craven Cottage.
Sanchez was beaten at his near post by Josh King for Fulham’s first goal, with the effort appearing to slip through his grasp. The Chelsea goalkeeper then spilled another attempt in the second half, allowing Gonzalo Garcia to capitalise and score.
Although Chelsea ultimately held on for three points, the defensive uncertainty provided a major talking point after Alonso’s first Premier League match in charge.
The decision to bring in Emi Martinez so soon after that performance underlines the seriousness of Chelsea’s concerns.
Martinez brings a very different profile to the goalkeeping department. The Argentina international has developed a reputation for his commanding personality, experience in major matches and ability to perform under pressure.
His arrival also gives Alonso an experienced goalkeeper capable of competing immediately for the starting position.
Martinez brings major experience to Stamford Bridge

Emi Martinez has built an impressive reputation since establishing himself as Argentina’s first-choice goalkeeper.
He was a key figure in Argentina’s rise to the top of international football and played a decisive role during the country’s successful run at the 2022 World Cup.
At club level, Martinez has also enjoyed considerable success with Aston Villa, including helping the club win the Europa League last season.
That combination of international pedigree and European experience makes him an intriguing addition for Chelsea, particularly as Alonso attempts to build a squad capable of competing across several competitions.
At 33, Martinez is considerably older than many of Chelsea’s recent recruits, but his experience could be valuable in a squad containing several young players.
Chelsea already have Mike Penders, signed from Genk for £17m, among their goalkeeping options. Penders is expected to make his debut in the Carabao Cup against Luton Town, meaning Alonso will now have several options to consider.
Why Aston Villa are willing to sell Emi Martinez

Aston Villa’s decision to part with Emi Martinez is closely linked to their own recruitment activity.
Villa signed Japan goalkeeper Zion Suzuki from Parma for around £30m earlier this month, paving the way for Martinez to leave the club.
The Argentine had also been the subject of interest from Juventus earlier in the summer transfer window, but that proposed move collapsed after concerns surrounding a finger injury.
Juventus subsequently turned to Tottenham goalkeeper Guglielmo Vicario on loan instead.
Martinez’s move to Chelsea therefore represents another opportunity for the goalkeeper to remain at a major European club while Villa continue reshaping their squad.
For Villa, the deal also allows them to move forward with Suzuki as their new goalkeeping option while receiving a fee for a player who had already been made available for transfer.
Chelsea and Villa continue remarkable transfer relationship

The Emi Martinez deal is also the latest chapter in an increasingly active transfer relationship between Chelsea and Aston Villa.
The two clubs have completed several significant transactions in recent seasons, including Chelsea’s record-breaking £117m acquisition of Morgan Rogers from Villa.
There has also been movement in the opposite direction, with Alejandro Garnacho joining Villa on an initial loan deal last month.
Nicolas Jackson has been completing a medical at Villa Park as he prepares to join Unai Emery’s side in a deal valued at around £65m, further strengthening the connection between the two clubs.
Chelsea and Villa were also involved in the controversial transaction involving Ian Maatsen and Omari Kellyman, a deal that was widely described as a “PSR swap” amid scrutiny of Premier League financial regulations.
The latest agreement shows that the relationship between the clubs remains particularly active during this transfer window.
A new battle begins at Chelsea
The arrival of Emi Martinez could now create one of the most interesting selection battles in Alonso’s early Chelsea reign.
Sanchez has been the club’s first-choice goalkeeper since 2023, but the pressure surrounding his position has increased dramatically after the Fulham victory.
Martinez, meanwhile, arrives with a wealth of experience and a reputation for thriving in high-pressure situations.
Chelsea’s decision to spend £7.5m on an established international goalkeeper just days before the transfer deadline suggests that Alonso and the club’s hierarchy believe competition is necessary.
The move may not automatically mean Sanchez has lost his place, but it ensures that Alonso now has a proven alternative.
For Emi Martinez, meanwhile, the transfer provides another major opportunity in the Premier League.
After helping Argentina conquer the world and Aston Villa compete in Europe, the goalkeeper is now heading to Stamford Bridge with the chance to prove himself once again at the highest level.
And with the summer transfer window approaching its dramatic conclusion, Chelsea’s £7.5m gamble could prove to be one of the most consequential late moves of the window.
