Arsenal have officially confirmed Jakub Kiwior's permanent move to FC Porto, but the announcement came in a rather unexpected way—tucked inside a routine loan watch roundup post instead of a dedicated news item or social media update.

The Gunners broke their silence on Monday morning, stating: "Jakub Kiwior’s move to Porto has now become permanent following the Dragaos’ Liga Portugal title triumph last weekend." It's a low-key farewell for a player who made 68 appearances across two-and-a-half seasons at the Emirates, winning the Community Shield along the way.

Porto had already announced the deal last week, revealing they'd activated their option to buy the Polish international. The Portuguese giants secured Kiwior on a long-term contract running until 2030, with a fixed fee of €17m plus up to €5m in potential add-ons. Arsenal also negotiated a €2m sell-on clause, meaning they'll pocket an extra €2m if Porto ever sells the defender—regardless of the price tag.

When factoring in the €2m loan fee Arsenal received last summer, the total potential value of the deal reaches €26m (£22.5m)—a tidy profit on the €20m (£17.6m) they paid for Kiwior back in 2023.

The timing of the move makes sense: Kiwior recently helped Porto clinch the Liga Portugal title, which likely prompted the club to finalize their summer business early. With two league games still to play, Porto are now in full celebration mode, and making Kiwior's loan permanent marks the start of their off-season planning.

For Arsenal, it's a quiet end to a solid chapter. Kiwior's time in north London may not have made headlines, but the club's smart business—and the defender's trophy-winning loan spell—shows how modern transfers can work behind the scenes.
