Arsenal boss Mikel Arteta says Gabriel Martinelli is 'very close' to a starting spot.
The Brazilian came off the bench to make it 2-1 in injury-time against Crystal Palace.
Asked how close Martinelli is to a starting spot, Arteta said: "Very close. He needs to keep fighting to be closer and closer.
"We need to understand where the boys are in the phase of their development and what they have done already this season and last season.
"I know that we want to play with 11 academy players under 20, but guys, who is doing that? We are doing more than anybody and they are going to have the chances, they are earning their chances, it's not like we are giving the chances. They are earning the chances and it's a joy to have them with us."
