Arsenal have announced the signing of Lille defender Gabriel Magalhaes.

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 €25m.

Gabriel joins fellow Brazilians David Luiz and Willian, the latter having recently joined on a free transfer from Chelsea, in north London. 

The defender joined Lille in January 2017, having started his career in Brazil with Avai.

Arsenal manager Mikel Arteta said on the club website: "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."

It's understood Arsenal are 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 at Wembley.

Arsenal technical director Edu revealed there had been plenty of interest in Gabriel's signature but the player said the history of the club had been a big draw.

Gabriel told Arsenal Digital: "So many fans were sending me messages asking me to join Arsenal, and that played a big part in me signing for this club.

"I know the history and traditions of this club and it is a pleasure being here. I am very happy and hope I can contribute to many titles with the Arsenal shirt,"

"It was a very surreal experience, there were offers coming from a few different clubs. I spoke a lot with my family and my agents, I also spoke with some of Lille's directors.

"But as I said, this club’s history and traditions and the team project for the next few years were very motivational for my decision to come here.

"So here I am, wearing the Arsenal shirt, I will give my best for it."

The defender joined Lille in January 2017, having started his career in Brazil with Avai.

Earlier on Tuesday, Arsenal had confirmed Ken Friar is to step down as executive director and become the club's life president at the age of 86.

Friar has worked for the Gunners for 70 years, having started out in the box office in 1950 before becoming club secretary in 1973 and then managing director 10 years years later.

He held that position until 2000, when he changed role and took charge of Arsenal's move from Highbury to the Emirates Stadium.
