Arsenal defender Jakub Kiwior will join FC Porto permanently at the end of the season for around £14.7million, with a further £4.31m due in potential add-ons. Kiwior was loaned to the Portuguese heavyweights this summer.
The Polish international made 68 appearances for the north Londoners having joined the club in the summer of 2022 in a deal worth £20m. However, with Mikel Arteta adding the likes of Cristian Mosquera and Piero Hincapie to his ranks last summer, Kiwior's future at Arsenal looked finite.
This season, the 26-year-old has been a key player for Porto, making 25 appearances for the club, who won the Portuguese title at the weekend. Arsenal even sent a message of congratulations to Kiwior on their website after they wrapped up the championship.

However, in regards to his exit, the news was confirmed by Porto, who also revealed they have placed a huge release clause of £60.4m on his name. They released a statement which read: "FC Porto exercised their option to buy 100% of the Polish international's rights, signing him until 2030.
"FC Porto has exercised the purchase option stipulated in the loan agreement with Arsenal FC and will now permanently own the sporting registration rights and 100% of the economic rights of Jakub Kiwior for a fixed fee of €17million (£14.7m), plus a maximum variable remuneration of £5million (£4.31m) depending on the achievement of certain objectives.
"Arsenal FC will retain a fixed amount of €2 million in any potential future transfer of the player. It is further informed that FC Porto has signed a contract with the Polish international defender valid until June 2030, with a release clause of €70m (£60.4m).

"Arsenal FC will assume responsibility for the solidarity mechanism due to third parties, and FC Porto declares that this transfer did not involve any intermediary intervention."
The transfer decision comes a matter of days after Arsenal sent a congratulatory message to Kiwior via their loan watch article on the club website.
They wrote: "Congratulations from all of us at Arsenal go to Jakub Kiwior, who lifted the Liga Portugal title with Porto after a 1-0 win over Alverca on Sunday night."

In November, Kiwior opened up on how he told Arteta personally he wanted to depart the Emirates Stadium for more game time elsewhere. In an interview with the Polish FA's website, he said: "We already knew then that I would go on loan to Porto.
"The coach emphasised how big the club was and wished me luck. The earlier conversation, when I asked for the loan, was more difficult.
"I’d never done this before, but I felt the time had come to speak with him face to face. He understood me and supported me.”
