The defender is set to replace Hector Bellerin after the Spaniard picked up an injury.
The French defender is set to be drafter in for Wednesday’s pivotal game against the German giants, with them looking to repeat their infamous win at the Emirates last time around.
They will be without young full back Bellerin though, who impressed in the first game against Pep Guardiola’s side, after he picked up an injury that ruled him out of the game.
Wenger though, has no fears that Debuchy will be in good condition to step up and replace the Spaniard.
“Debuchy will play and I’m confident,” he told arsenal.com.
“I trust Debuchy, he is a 100 per cent educated player in the box and in training. Fortunately he played a full game against Sheffield Wednesday and physically he should be well."
Given his experience, there is no doubt that Debuchy should be an able replacement for Bellerin.
Having spent the majority of this season on the bench though, he is sure to be somewhat rusty with the recent game against Sheffield Wednesday not likely to have made much difference.
However, the biggest concern that Wenger will have will be the disruption it causes to his side, with a settled side and a consistent defence having considerably helped their good form of late.
He, and Debuchy, will be hoping that isn’t the case given their Champions League hopes very much rest on a positive display at the Allianz.
