Les Bleus head into their final Group E game knowing that they are already in the second round thanks to two wins from their opening two fixtures.
However, Debuchy is eager for the side to beat the Ecuadorians and end their group campaign at the top of the standings with maximum points.
"We need to avoid taking our foot off the gas even if there is not a huge amount at stake," he told FIFA.com. "We want to win this match and maintain our positive dynamic in order to prepare well for what is to come."
France are likely to face either Argentina, Nigeria or Iran in the last 16 of the tournament.
