Check out our list of the most expensive player sales in Chelsea's history.
When Roman Abramovich became the new owner of Chelsea in the summer of 2003 the club instantly became one of the richest in world football.
In the more than two decades since, the Blues have won five Premier League titles and enjoyed sustained success in Europe, including twice being crowned UEFA Champions League winners.
While incoming signings have often made headlines in West London, the club has also made history when it comes to player departures.
After a protracted saga surrounding his future Enzo Fernandez joined Manchester City this summer for a reported £125million fee.
In doing so the Argentine became the first player ever to move for more than £100m on more than one occasion.
It's no surprise then that Fernandez tops the list of Chelsea's most expensive outgoings.
What may come as a surprise is that nearly half of players to feature in the all-time top 10 departed this summer as Xabi Alonso looked to reshape his squad upon his arrival.
Fernandez, Marc Cucurella, Nicolas Jackson and Andrey Santos all left in recent months, with fellow recent departure Liam Delap narrowly missing out on a place following his move to Nottingham Forest.
