18-year-old Martinelli has only been at the club a year, arriving from Ituano last summer.
His first season at the club has seen the teenager become somewhat of a revelation, as well as demonstrating outstanding form.
The Gunners have a history of successful Brazilians at the club and one of the most prominent ones Gilberto Silva spoke of his high expectations from a maturing Martinelli.
Speaking to the club’s official website, Silva said:
“I’m pleased that Arsenal has Brazilian players.”
“I think it’s fantastic after some of the Brazilian players that followed us not quite hitting the heights but now Martinelli and David Luiz are at the club.”
“David made the transition from a rival Chelsea and joined Arsenal, a club that needs no introduction.”
“Then you have Martinelli, a promising youngster not just for Arsenal, but he’s being talked about in Brazilian football and he made a very good start.”
“He’s doing well and shown his bravery.”
“He wore the Arsenal shirt as if he were still playing with his friends at his previous club.”
“I’m pleased that Arsenal managed to get the deal done and he’s in a good position to follow in the footsteps of all the Brazilian players that Arsenal has had.”
“He’s got a great future ahead of him. He’s a Brazilian with very interesting prospects.”
“The way he started to make himself stand out isn’t easy is it?”
