Gabriel Martinelli has signed a new long-term contract at Arsenal.

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.

The London Evening Standard says 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."
