As expected, Lille defender Gabriel Magalhaes will sign for Arsenal after completing his medical, as Napoli had taken a step back on the €30m deal.
Multiple sources including Sky Sport Italia, Sportitalia, Fabrizio Romano and more are all confident the medical tests were done today.
He will therefore put pen to paper on a five-year contract this evening, with a salary starting at €2m per season.
The transfer is believed to be worth €26m plus up to €4m in various bonuses.
Napoli had agreed a deal with Lille several weeks ago, as part of their negotiations to take striker Victor Osimhen.
However, the completion depended on Napoli first selling at least one out of Kalidou Koulibaly, Nikola Maksimovic and Arkadiusz Milik.
With the sales taking too much time, the Partenopei opted not to increase their offer when Arsenal came in with an improved bid.
Gabriel is a 22-year-old Brazilian centre-back who joined Lille from Avai FC in January 2017, experiencing loan spells at Troyes and Dinamo Zagreb.
