The Gunners meet Swiss side FC Basel at St Jakob-Park on Tuesday night in their final Group A fixture of the 2016/17 European season.
"We have the same squad as we had on Saturday," said Wenger.
"I have to decide the starting XI tomorrow, but I want to win the game and do our job, and continue to win the games we play.
"We have a squad that is united. When a guy is in good form and has confidence, it's more dangerous to stop him than to keep him going.
"You never know what can happen in Paris. PSG are favourites to win, but we can assess that scoreline at half-time and see where we go."
However, the Frenchman was not too concerned whether or not his side tops Group A as there are some very even groups throughout the Champions League this term.
"Is there a difference between finishing first and second? If you look at the teams, not really, no," he added.
"So we'll see what happens tomorrow with the final results. It looks quite even, whether you finish first or second."
