Gabriel Martinelli has signed a new long-term contract at Arsenal, the club have confirmed.
The Gunners youngster, a summer signing from Brazilian side Ituano, has been an instant hit in north London, scoring 10 goals in his debut season in England.
He follows in the footsteps of teammate Bukayo Saka, who also committed his future to the club this week after signing a new four-year deal.
Standard Sport understands the 19-year-old has signed a four-year deal with the option of a fifth, earning a salary rise after a good start to life in England.
"I am very happy that Gabi has signed a new contract with us," Gunners head coach Mikel Arteta said.
"He is a very talented young player and he has impressed us with his performances, attitude and work-rate. We are looking forward to getting him back to full fitness and to watching his development at our club."
Martinelli scored four times in his first two appearances in the League Cup this season and three in the Europa League group stages.
He scored his first Premier League goal against West Ham in December last year, notching twice more in the league since then – including a memorable solo effort against Chelsea at Stamford Bridge.
