Before this summer transfer window, many Chelsea fans were concerned that Madueke and Felix would become liabilities, unaware that Chelsea had managed to sell them for a "hefty" transfer fee. They effectively cleared out two players not fitting into Maresca's plans and secured a total transfer fee of €106 million, including a sell-on fee for Felix.

According to Transfermarkt data, Chelsea signed Madueke from PSV for €35 million in January 2023 and sold him to Arsenal this summer for €55.4 million, which also included €4.6 million in add-ons.

According to Transfermarkt data, Chelsea acquired Felix from Atletico Madrid for €52 million during the summer transfer window in 2024. This deal was more of an accounting maneuver, as Felix's market value at the time was only €30 million, resulting in a premium of €22 million for his acquisition. This summer, they sold him to Al Nassr for a fixed fee of €30 million plus €20 million in add-ons and a sell-on fee.
The cost for Chelsea to sign Madueke and Felix was €35 million + €52 million = €87 million.The transfer fees received from selling Madueke and Felix were €55.4 million (excluding add-ons) + €50 million (including add-ons) = €154 million.Madueke's transfer fee was calculated in euros based on £48 million plus £4 million in add-ons. The calculation for Madueke's transfer fee excludes add-ons, while Felix's includes them, which might relate to the ease of activation. In summary, Chelsea successfully offloaded Madueke and Felix this summer and recouped their costs, showcasing exceptional management.
