Eddie Nketiah netted twice as Arsenal made it four wins three wins out of three in pre-season.
Boss Unai Emery opted for a youthful side spearheaded by the 20-year-old Englishman, who also scored the winner against Bayern Munich this week.
Joe Willock also got himself on the scoresheet with a neat finish in the dying seconds of the game.
“I’m really happy but last year in small moments when we could give him chances to be on the pitch he did very well,” he said.
“His progress can confirm, we want progress with every player.
“He has a very good attitude and they need experience, minutes and confidence. The young energy is very important.
In response to Nketiah being afforded more game time this season, Emery added:
“Aubameyang plays some time on the wing,” he said. “Last year we had Lacazette, Aubameyang and Welbeck. They had space to play.
“We want to give the chances to Nketiah. Every young player if they deserve to be here we’ll help them.”
