Gnabry made his debut for his country in their World Cup qualifier away at San Marino after making a great start to life as a Bundesliga player.
Arsenal fans will be well aware of the 21-year-old after he broke into their team four years ago.

Since then, he’s been very impressive, scoring four goals and assisting another in nine games so far.

We wonder if Wenger and Arsenal fans will be regretting letting Gnabry go when they see him in this form?
