Gabriel Martinelli admits he was starstruck when first meeting Arsenal team-mate Pierre-Emerick Aubameyang.

The 18-year-old kicked off his Arsenal career with a fine double in the 5-0 win over Nottingham Forest on Tuesday.

Speaking after the game, the summer signing from Ituano revealed it was surreal meeting the famous striker.

He told Globo Esporte: "It hadn't sunk in yet. I arrived for lunch on the first day, I'm eating there, Aubameyang arrives and sits next to me, speaking Portuguese with me, 'Tudo bem?', trying to communicate.

"You see, the guy so good, humble. I was like: 'Man, Aubameyang, who I saw on TV, came to talk to me!"

"He's also a guy who gave me a lot of support at the club, trying to communicate with me. I have to thank everyone at the club. They're very nice people."
