Porto trigger buy option for Arsenal defender Jakub Kiwior in £19m permanent transfer

According to an official statement released by the club on Monday, Porto have triggered the purchase clause for Kiwior. The 26-year-old originally arrived on loan for a £1.7 million fee, but the Portuguese side have now secured him permanently. Porto confirmed: "FC Porto has triggered the purchase option included in the loan agreement signed with Arsenal FC and will now definitively hold the sporting registration rights and 100% of the economic rights of Jakub Kiwior for a fixed fee of €17 million (£14.5m), plus a variable component that may reach €5 million (£4.3m) subject to the achievement of certain objectives."

The total package could reach £19m if all performance-related add-ons are met. Arsenal have ensured they retain a financial interest in Kiwior, who made 68 appearances for the London club after joining from Spezia Calcio for £16.7m in January 2023. The official announcement noted: "Arsenal FC has retained a fixed amount of €2 million from any future transfer of the player."

Kiwior has established himself as a vital component of the defence this season, racking up 38 appearances and playing 3,022 minutes across all competitions. He contributed two assists and played a pivotal role in helping the side secure the Liga Portugal title. To protect their investment, Porto have locked him down on a massive contract. The club announced that they signed the Poland international defender to a "contract valid until June 2030, with a release clause set at €70 million (£60m)."

With his future and the Portuguese league title firmly secured, Kiwior will now focus on anchoring the backline as Porto prepare for next season's Champions League campaign. His long-term commitment provides stability, ensuring the club possess a reliable defensive cornerstone to mount sustained challenges for both domestic honours and continental glory over the coming years.
