The talented Frenchman has been called into the Arsenal squad for the Champions League tie.
Arsenal take on Bayern Munich tonight hoping to pick up where they left off the last term they faced the German champions and emerged as 2-0 victors at The Emirates Stadium.
The Gunners are however experiencing a mini-injury crisis at the club. They are without Alex Oxlade-Chamberlain, Theo Walcott and Aaron Ramsey after they picked up recent injury problems. Now Spanish defender Hector Bellerin has pulled out of the team ahead of the game.
Which has seen Jeff Reine-Adelaide brought into the first-team.
Reine-Adelaide was a star for Arsenal during the Emirates Cup this summer. Signed from RC Lens this summer the 17-year-old looks like a real talent for the future at Arsenal.
Recently he has been playing in Chile in the FIFA Under-17 World Cup with France and scored in a penalty shootout against Costa Rica in the second round - where his nation were unfortunately knocked out.
He returned to London this week and has immediately found himself in the first-team training sessions ahead of the Bayern fixture.
He has been in training, tussling with countrymen Mathieu Dbuchy and Francis Coquelin and also giving chase with Calum Chambers.
Arsenal fans would love it if JR-A can get a run-out and impress in the coming weeks.
