Arsenal defender Jakub Kiwior has completed a £14.6 million ($19.3 million) move to Porto.
The 26-year-old spent last season on loan with Porto and played 36 times across all competitions as the Portuguese side secured a domestic title.
Porto have exercised an option to keep Kiwior on a permanent deal from Arsenal with a possible £4.3 million in add-ons.
Kiwior made the move to north London for £17.3 million from Italian side Spezia in January 2023, and went on to play 63 games for the Gunners.
