The former Manchester City striker has signed for the Gunners today, rejoining Arteta who spent time as City assistant manager before moving to London giants.
Giving an insight into the pair's recent discussions, Gabriel Jesus said: “We spoke a couple of times about the club, the players, the project and the future. I believe 100 per cent in Mikel. I had a very good time with him before, he's a very good guy and a very good coach as well.
“He helped me a lot [at Manchester City]. We would always stick together after the training sessions and do some finishing or something. He's a very intelligent guy and was an amazing player, so if he knows something he can teach me or the young players."
Another factor in the 25-year-old's decision-making process was the size of the club he was joining, with Gabriel Jesus revealing he used to enjoy watching Arsenal teams when he was growing up in Sao Paulo, especially one player in particular.
“I followed Arsenal when I was young because of [Thierry] Henry," Gabriel Jesus added. “Obviously I didn't follow too many European teams but when I saw some of the players that played here, I was like “wow, this club is big." When I played against Arsenal I was looking at the Emirates and it was a very good stadium, so I'm very excited to play here.
“I'm so happy to sign for this big club. Since day one when I knew I could come to play for Arsenal, I was happy. I know the staff, I know some players, the Brazilian ones. I know there are a lot of top players. They are young and I'm still young as well, so I am so happy to be here to help. I come to help, to learn as well and to try to do my best."
