Arsenal management are delighted with progress of Serge Gnabry.
The 17 year-old German winger was outstanding for the U21s in their win over Reading this week.
Coach Terry Burton told arsenal.com: "[His performance] comes from the benefit of playing with more experienced players. When you make runs, they tend to find you a bit earlier; and also when you are in with that quality of player, you want to show them that you are a good player too. I thought for an hour he was very good."
