Arsenal have announced the signing of defender Gabriel Magalhaes from Lille.
The 22-year-old centre-back has signed a long-term contract at the Emirates Stadium for a fee understood to be in the region of £22million.
Gabriel will link up in north London with fellow Brazilians David Luiz, Gabriel Martinelli and Willian, the latter having recently joined on a free transfer from Chelsea.
The defender joined Lille in January 2017, having started his career in Brazil with Avai. Arsenal manager Mikel Arteta said: "He has many qualities which will make us stronger as a defensive unit and as a team.
"He has proved with Lille that he is a defender with many outstanding attributes and we are looking forward to watching him grow as an Arsenal player."
Arsenal are also in advanced talks to bring Dani Ceballos back to the club on another season-long loan from Real Madrid as Arteta continues to look to strengthen the squad. The Gunners are also close to announcing a new and improved deal for captain Pierre-Emerick Aubameyang, who helped the FA Cup winners beat Liverpool in the Community Shield.
