The former Stoke City player was awarded a rare start by head coach Thomas Tuchel who opted to rest wonderkid Kylian Mbappe.
But it wasn't a night to remember despite the Cameroon international opening the scoring.
With the score at 1-1 in the first half, he somehow managed to hit the post despite being on the goal line when he made contact with Christopher Nkunku's goal-bound effort.

"I thought Nkunku was going to give it to me - and than I thought the defender was going to get it," he said, as per The Mirror.
"I wondered if I was offside and it all happened very fast. I touched the ball, it hit the post and, well, it's a real shame because the ball was going in.
"I'm sorry about that."
With eight games remaining PSG still hold a 20 point lead over second-place Lille.
