Arsenal regained The Emirates Cup this weekend with wins against Lyon and Wolfsburg, but the big takeaway was the sensational introduction of Jeff Reine-Adelaide.
The teenager was a low key summer signing from French side Lens, but impressed manager Arsene Wenger enough to link straight up with the first team.
The 17-year-old made an instant impression with his confidence on the ball and willingness to take players on. It's no exaggeration to say he was the most exciting player on the pitch in the Wolfsburg win on Sunday.
His performance caught the attention in his homeland and around Europe, with French website But! Football Club reporting on his piece of trickery which beat Belgian international and former Chelsea midfielder Kevin de Bruyne.
They wrote: "At least one can say is that the young winger is already bursting at the Gunners. After making his debut at the Emirates Cup against Lyon (6-0) yesterday, Reine-Adelaide stood out Sunday against Wolfsburg humiliating Belgian star of Kevin De Bruyne of Wolfsburg."
MadeInLens ran a headline entitled 'Reine-Adelaine won the tournament at The Emirates', writing: "The Gunners fans will quickly remember the name of the former Lens player. I
"Indeed, the midfielder formed at RC Lens is to be credited with very nice play, and a decisive pass for the winner from Theo Walcott, and he was designated as "Man of the Match" for his performance."
Belgian newspaper Nieuwsblade also reported on Reine-Adelaide's display, taking an interest due to De Bruyne.
They reported: "The 17 year old Frenchman even made De Bruyne dizzy with a sublime turn. A name to remember!"
Arsenal's best kept secret? Not any more
Arsenal have let the world know about the talent they have at their disposal, but Arsene Wenger will not rush his development.
While he put Cesc Fabregas straight into the team a decade ago, he has been more cautious with young players of late.
Reine-Adelaide will join Gedion Zelalem, Alex Iwobi, Dan Crowley, Krystian Bielik and Serge Gnabry in the queue for first team opportunities, and Wenger has already told the club website he wants the young Frenchman to stay rather than go out on loan, to learn alongside the first team.
