Pierre-Emerick Aubameyang is on the bench for Arsenal in tonight's Europa League clash against Standard Liege.
And the striker certainly likes what he's seen from one of the Gunners' most promising players - who could soon be rivalling him for a starting berth in Premier League games.
Gabriel Martinelli joined from Brazilian outfit Ituano in the summer transfer window and he's already made a big impression.
On his full Arsenal debut last week he scored twice in a 5-0 win over Nottingham Forest in the Carabao Cup.
And on his second start for the Gunners, he's netted another brace.
The first was a brilliant header from Kieran Tierney's cross, while the second was a lovely crisp finish into the bottom corner following fine work down the left-hand side.
Joe Willock added another shortly after with his second goal of the competiton.
But all the talk is about Martinelli.
As the cameras panned towards the Arsenal bench after Martinelli's second goal, Aubameyang was seem smiling alongside Matteo Guendouzi.
The teenager did reveal last week that Aubameyang has been helping him to settle in England.
"[The transfer] 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: '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.
"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."
