Overview
- FC Porto said they exercised the buy option to make Kiwior's move permanent, with the announcement landing hours before Arsenal's Champions League semi-final.
- The transfer carries a €17 million fixed fee with up to €5 million in bonuses tied to targets.
- Kiwior signed a contract to June 2030 that includes a €70 million release clause, which sets a clear buyout price for any bidder.
- Porto now own 100% of his economic rights, while Arsenal keep a fixed €2 million on any future sale and will handle solidarity payments to his training clubs.
- His 38 appearances in a title-winning loan season convinced Porto to lock in a first-choice defender for next season's Champions League campaign.
