Gabriel has revealed how Mikel Arteta played a key role in his decision to join Arsenal.
Lille allowed the Brazilian to choose his destination after a number of clubs met their transfer demands.
Manchester United, Napoli and Everton were all keen on the Brazilian centre-half.
But the Gunners won the race, thanks in large part to their manager.
"[Edu and I] had several chats about Arsenal and the new project, we had many good conversations," Gabriel told Arsenal Digital.
"As the days went by I was getting very excited about it, then I had a call from the coach and that was very reassuring.
"Having the coach himself calling you to say he wants you in his squad motivates you a lot. That is the very reason I am here today.
"We did not talk about [details], he just told me he is aware of my quality, my capacity and how far I can go. He also said he will be very demanding with me.
"I know he is a great coach and I will make progress with his help."
