Chelsea's unusual summer saw 39 players leave the institution between sales and loans, a figure that adds to the departure of four young footballers who were disconnected from the institution. The English club's transfer market was marked by departures, with the most important sale being that of Enzo Fernández, who was transferred to Manchester City on the last day of the market for 125 million pounds, some 145 million euros, a figure that equalled the transfer record in the history of the Premier League.

The Chelsea also concreted the sales of Andrey Santos for 56.3 million euros, Nicolas Jackson for 55.5 million euros, and Marc Cucurella for 55 million euros. Additionally, Liam Delap left London for around 52 million euros. The club recaudó alrededor de 448 millones de euros, a figure that established a new record for a single transfer window.

The Chelsea's transfer policy allowed the club to surpass its own record and remain above other big sellers in European football, with Aston Villa recaudó alrededor de 360 millones de euros and Manchester City, unos 337 millones.
