Off the back of a world-conquering summer in the United States, Chelsea are back in business on the Premier League scene as they look to improve on a fourth-placed finish last term.
The newly-crowned Club World Cup winners are currently occupying second spot in the top-flight standings after three matches, possessing seven points and sitting just two points behind Liverpool, who have blown the transfer window away this summer.
Despite the Reds' signings being impossible to ignore, Enzo Maresca will be focusing on what his Chelsea side can do over the next 10 months, with Champions League football back at Stamford Bridge to partner a possible Premier League title hunt.
Here, Sports Mole analyses Chelsea's summer transfer window and determines whether their market activity was successful or not.
Chelsea summer transfer window: Blues continue their stockpiling of attacking talent
Chelsea's intent to bolster their squad with new attacking talent was on show from very early on in the window, with the Blues triggering the £30m relegation clause in the contract of Ipswich Town striker Liam Delap, who impressed during his maiden campaign in the Premier League last term.
The 22-year-old has the potential to be the West Londoners' first-choice forward for the next decade and could be the heir to Harry Kane's England throne, but the youngster suffered a major bit of misfortune last month, picking up a hamstring injury.
Also through the Stamford Bridge door near the beginning of the summer, Joao Pedro has been one of the most notable instant hits in recent history for Chelsea, with the Brazil international bagging a brace against Fluminense on his debut at the Club World Cup.
The former Watford and Brighton & Hove Albion man has shone at every step of his career to date and has so far silenced doubters who suggested that he would not be capable of providing enough goal contributions competing at the very top of the English and European scene.
Joining compatriot Delap in West London, Jamie Bynoe-Gittens is back in England after a five-year experience on the books of Borussia Dortmund, who nurtured the winger from an Under-18s player to one which is ready to explode onto the Premier League stage in 2025-26.
Portugal international Pedro Neto is currently keeping the ex-Manchester City youngster on the bench in the Premier League, but at the age of 21 and with plenty of football on the calendar for the Blues this year, it is only a matter of time until Gittens gets his chance to shine.
Following in the footsteps of 2024-25 Jadon Sancho, Argentine winger Alejandro Garnacho has made the switch from Manchester United to Stamford Bridge, although the winger has taken the permanent route, with a £37m deal hashed out between two English powerhouses.
Once a fans' favourite at the Theatre of Dreams, Garnacho is no stranger to a moment of magic but fell victim to a change of system under the stubborn reign of Ruben Amorim, who deemed the six-goal forward surplus to requirements ahead of the summer window.
Walking down a well-trodden path from the South coast to West London, Facundo Buonanotte was the subject of a curious-looking loan deal from Brighton, whilst Jorrel Hato and Mamadou Sarr have all been recruited to bolster the backline options.
Chelsea summer transfer window: Outgoings make room and make sense
Like the majority of recent summers at Stamford Bridge, there has been a major churn of players through the revolving doors, with numerous youngsters moving away either on temporary or permanent deals to further their careers elsewhere.
Lesley Ugochukwu moved to newly-promoted Burnley in a £24m deal and was followed by Albania international Armando Broja to Turf Moor just a day later for £19m, meaning that the Blues will see plenty of familiar faces in Lancashire during their November trip.
A member of Chelsea's Champions League-winning side has left the club on a permanent basis, with Ben Chilwell switching to sister club Strasbourg on a two-year deal, in which time the left-back will hope to regain his spot as a Three Lions regular.
Unwilling to play third fiddle to Delap and Pedro in the English capital, Nicolas Jackson was granted his wish of being Kane's backup at Bayern Munich, with the Senegal international moving to the Bavarian giants on a season-long loan for 2025-26.
Likened to the Blues' hardened defenders of the past, Alfie Gilchrist secured a permanent transfer to West Bromwich Albion for around £1.9m, providing another example of how top-level academies transition more often to the selling list than the first-team pitch.
Some of Chelsea's Conference League stars have not made the cut this season and are preparing for new adventures elsewhere, with Christopher Nkunku and Kiernan Dewsbury-Hall moving to AC Milan and Everton respectively.
