Arsenal boss Mikel Arteta praised Eddie Nketiah after their 2-2 draw with Fulham.
Nketiah jumped from the bench to score.
Arteta said, "Great. He looks a real threat at the moment. He's in a good moment, he's full of confidence. I saw it straight away when I told him he was coming in the second half the fire in the eyes.
"He's got an eye for goal and the way he finished the action was top.
"It's difficult to leave all the players out. When I see on the bench there are a lot of players who still haven't played. At the moment though we are once a week, when we are two a week it's going to be a completely different scenario how we are prepared for that."
