Belgian winger Eden Hazard remains the biggest departure from Chelsea in the club's history.
The €120m deal that saw Hazard move to Real Madrid in the summer of 2019 is the club record for a sale.
Hazard spent seven seasons at Stamford Bridge and he netted 110 times in 352 matches across all competitions.
After moving on to Real Madrid, Hazard failed to find his best form and he retired from football in 2023 after making 76 appearances for the Spanish giants.
Kai Havertz's €75m transfer to Arsenal in 2023 is the club's second biggest departure and after initially looking overpriced, the German striker is now starting to find his feet at the Emirates Stadium.
Mason Mount moved to Manchester United in the same transfer window for a sizeable fee and that deal looks to have been the right call for Chelsea.
The top five is completed by Diego Costa and Oscar following their big-money departures, while the likes of Juan Mata and Nemanja Matic also feature on the list.
