Magalhaes, 22, has put pen-to-paper on a five-year deal with the Gunners after snubbing interest from Napoli, Paris Saint-Germain and Manchester United. 

On the news, Arsenal’s technical director Edu said: “We are delighted to have signed Gabriel.

“He is a player we have been studying for a while and he was in demand from many clubs, so we are proud to have agreed and completed this transfer with Lille and the player.

Gabriel’s representative, Guilherme Miranda, revealed last week that his client rejected more lucrative offers to join the Gunners, citing the key role the aforementioned duo played in his final decision.

He told journalist Freddie Paxton: “Arsenal was nowhere near the best proposal [money-wise].

“Gabriel chose them over more lucrative offers because Edu convinced us of the project.

“It’s 100 per cent because of Edu Gaspar and [Mikel] Arteta.”

“Gabriel is a player of high quality and Mikel and his coaches are looking forward to integrating him into the club.”

Gunners head coach Mikel Arteta added: “We welcome Gabriel to Arsenal. 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.”

The news was confirmed in a unique way, with the defender joining fellow Brazilians David Luiz and Willian on a Facebook Live video call.

Arsenal had teased the video with Willian and David Luiz, saying they would be joined by one other special guest, with many Gunners supporters speculating it would be Gabriel.

And true to form that is exactly how it happened, with Luiz saying on the FB Live: "Yes. There he is, he even has the shirt already, it is official."
