What happened
Jakub Kiwior's transfer from Arsenal to FC Porto has been made permanent, per Fabrizio Romano. The deal is structured as a €17m fixed fee, €5m in add-ons, and €2m owed to Arsenal from any future sale. A €70m release clause is included in Kiwior's new contract at the Estadio do Dragao.
Why it matters
The move resolves Kiwior's Arsenal future after his loan stint and gives FC Porto, fresh off their 31st Portuguese league title, a long-term central defender. The €70m release clause signals Porto's intent to protect the asset against future Premier League interest. For Arsenal, the sell-on percentage and add-ons preserve upside if Kiwior's value rises in Portugal.
What to watch
Watch for Porto's official announcement and Arsenal's reinvestment of the fee into their summer center-back search. Kiwior's playing role under Porto's manager will determine whether the release clause becomes relevant.
