Arsenal defender David Luiz has spoken about the youngster within the club who has the best mentality.
Luiz, who arrived at the club in the summer from Chelsea, was talking up talented teenager Gabriel Martinelli.
The youngster has impressed in the chances he has received this season, mostly in the Carabao Cup and Europa League.
Martinelli is only 18, but already has seven goals in all competitions with the Gunners.
"I always say, talents, I have seen many, but great mentality, I didn't see many," Luiz told 90min.com.
"And who arrives far? It's great mentality, not just talent.
"I'm not going to say to you about who is the most talented [at Arsenal], but the best mentality at the moment is Martinelli.
"He has a great mentality, especially because I know Brazilians at 18 years old.
"He's a top guy, a top player, but what makes me more impressed is the mentality in the training ground, the way he reacts after he scores goals.
"[After] scoring at Anfield, he continues to work, not asking already, 'I have to play, I have to play'. This is a great mentality.
"He's taking his opportunities step-by-step, always with the same focus and determination. He is so mature for his age."
