Where to start? Chelsea have been steadfast in their pursuit of what they believe to be low-cost, high-potential young players, adding striker prospect Marc Guiu (18) from Barcelona, Aston Villa midfielder Omari Kellyman (18), versatile Renato Veiga (20) from Basel and Villarreal goalkeeper Filip Jorgensen (22). They have also signed defenders Caleb Wiley (19) from Atlanta and Boca Juniors' Aaron Anselmino (19), with both immediately loaned back out. Supporters will be relishing Estevao Willian's arrival in 2025, after Chelsea saw off competition from Europe's elite to land the prodigious Palmeiras winger for £56m ($72m).
The club has deviated from that youth strategy, bringing in Kiernan Dewsbury-Hall (25) from Maresca's former club Leicester for £30 million ($39m) as a ready-made option for his system, and centre-back Tosin Adarabioyo (26) on a free transfer from Fulham. Their biggest spend to date though, which came out of left field, was the £54m ($70m) splurge on Wolves' Pedro Neto (24), as they added yet another winger to their ranks.
All of those incomings have led to questions over whether the squad has actually been improved, with Maresca the latest Chelsea manager to be left with a bloated group and not much time to cut it down. Their decision-makers still seem determined to add another attacker, with questionable talks ongoing over Atletico Madrid's Joao Felix and Napoli hitman Victor Osimhen still a target.
In terms of outgoings, the Blues have lost the vast experience of Thiago Silva after he returned to Brazil, while academy products Ian Maatsen and Lewis Hall were sold off for pure profit before the PSR deadline in June, alongside Omari Hutchinson. Elsewhere, deadwood in the form of Hakim Ziyech and Malang Sarr has finally been cut away.
However, there is still lots of work to do; the hierarchy seems determined to force Cobham graduates Conor Gallagher, Trevoh Chalobah and Armando Broja out of the club in a move that will not go down well with the fanbase. Meanwhile, Romelu Lukaku and Kepa Arrizabalaga - both on huge wages - are still on the books and need to be shifted in what remains of the window.
