Amid potential defensive injuries, Arsenal may consider recalling 25-year-old centre-back Jakub Kiwior from his loan spell at Porto. However, this is considered unlikely because the Portuguese club has an obligation to buy the Polish international for €17 million next summer. The defender has made 7 appearances and scored 1 goal in Liga Portugal this season. Kiwior has 40 caps and 2 goals for Poland, and his current market value is estimated at €25.00m by Transfermarkt.
