Arsenal teenager Gabriel Martinelli is grateful for the influence of David Luiz.

The teenager got a chance to shine for the Gunners in the Carabao Cup on Tuesday, scoring two goals in a 5-0 win over Nottingham Forest.

The attacker arrived from Brazil this summer after being spotted by the club's new technical director, former player Edu. And Martinelli says Luiz is helping him settle.

He said after the Carabao Cup game to reporters: "It was exceptional for me for David Luiz to come to the group, because he's Brazilian and helps me in everything in communication with fitness coach, or something I have to do.

"If I have questions I ask him how he speaks.

"Sometimes I ask how he speaks so he doesn't have to ask for me, so I can learn too, and he does help me."
