The Brazilian forward struggled for game time initially this season making just six appearances in their 13 Premier League games.
But the youngster has bagged three goals in their last two games and his teammate Ben White never doubted his abilities in training.
‘I see him every day, so it’s not really a surprise to me. He’s a very talented player and that’s what we are all starting to see,’ White told the Evening Standard.
Even the manager heaped praise on the talented youngster for his recent performances.
‘You cannot play every action at 100mph, it is impossible,’ Arteta said.
‘It is not very efficient for you because you burn yourself out after a few minutes, and then you just chasing a situation and not reading exactly what is needed.
‘Gabriel is doing much better at that. We have to try to do that without losing the passion, the energy and this capacity he has to just affect the game with the way he acts on the pitch.
‘He trains incredibly hard, he is always willing to do more and he is not scared or afraid to take risks, and that is what I like about him.’
