Chelsea confirmed 39 departures during the summer window as new head coach Xabi Alonso reduced the oversized squad at Stamford Bridge, generating between £300 million and more than £460 million in outgoing revenue. Enzo Fernandez joined Manchester City for £125 million, Marc Cucurella moved to Real Madrid for approximately £52 million and Nicolas Jackson transferred to Aston Villa for around £65 million. Chelsea reinvested between £280 million and £328 million, including a £117 million deal for Morgan Rogers from Aston Villa that made him the most expensive British signing in history. A reported deadline-day move for Monaco midfielder Lamine Camara did not ultimately go through, revising earlier reports that Chelsea had agreed a £47 million transfer and that the player was undergoing a medical. Chelsea will not play in European competition during the 2026-27 season, while the sales and squad reduction also address wage costs and compliance with Profitability and Sustainability Rules after several windows of aggressive spending under the Todd Boehly-Clearlake Capital ownership group.
