Arsenal team news: Bellerin injured and replaced by under the radar summer signing

The right back has been replaced by midfielder Jeff Reine-Adelaide in the Gunners squad.

Reine-Adelaide joined RC Lens in the summer.

The French youngster, 17, was named in the team of the European Under-17 Championship after helping his side secure the title.

He played in the 6-0 win over Lyon in the Emirates Cup and assisted Mesut Ozil in the win over Wolfsburg.

However it is Mathieu Debuchy who will come in at right back.

"I have confidence and trust in him. Physically he should be ready," Wenger said.

Arsenal beat Bayern at the Emirates two weeks ago through goals from Olivier Giroud and Ozil.

But their Champions League hopes remain in the balance after losing their opening two matches.

Arsenal need to get something from the Allianz Arena to keep progression in their own hands.

"We need to give a similar performance to when we played Bayern in the first game," Wenger said.

"I expect Bayern to play offensively and try to put us under pressure”
