The winger struggled for game time during his several years in north London, and struggled on loan at West Brom before deciding to depart and go back to play in the country of his birth.
However, Gnabry lit up the summer Olympic Games in Rio and finished the male’s football tournament as top scorer, and then bagged a hat-trick on his senior debut for Germany just a few months later.
The 21-year-old now looks like one of the most exciting prospects in European football at the moment, and of leaving the Gunners, Gnabry told Kicker, via the Mirror: “It was the right decision. Everybody who compares my development over the last four months to my time in England before that can’t come to a different conclusion.
“That was the main reason for the transfer – I wanted to get more playing time and it worked.
“Arsenal wanted to keep me, badly, but I had to look after my development.
“If a player does not perform well, a club has no sympathy and they do not want to keep him.”
It seems like after investing years of development and coaching in Gnabry, Arsenal might have lost him at exactly the wrong time.
What do you make of his development? And will Arsene Wenger regret losing the play-maker in the years to come?
