However, a defeat against France, coupled with Norway taking at least a point from Senegal, would leave their hopes of a top-two finish hanging by a thread.
In that scenario, Iraq would likely need to rely on qualifying as one of the best third-placed teams.
Having also exited the 1986 World Cup group stage with three defeats, Iraq remain without a single point in World Cup Finals history.
Their record of just one win from their last six matches suggests Arnold's men may have to wait a little longer for that historic breakthrough.
There is some encouragement in the fact that Iraq have scored in nine of their last 11 matches across all competitions.
However, that statistic may offer little comfort against the 2018 World Cup champions in the first-ever meeting between the two nations.
Team News and Prediction
France have been closely monitoring the fitness of defenders William Saliba, Dayot Upamecano, Theo Hernandez, and Malo Gusto in recent days, although there are no indications that any of them will miss Monday's match.
However, Theo Hernandez could reportedly make way for Lucas Digne as part of three changes to Deschamps' starting lineup.
Another expected adjustment could come in midfield, where Manu Kone is tipped to replace Aurelien Tchouameni.
After becoming the youngest French player to score on his World Cup debut since Thierry Henry 28 years ago, Bradley Barcola is also expected to replace Desire Doue on the left wing.
For Iraq, winger Ali Jasim was forced off during the second half against Norway after picking up a knock. The 22-year-old has since trained normally throughout the week and should be available for selection.
Goalkeeper Jalal Hassan has also recovered from a minor fitness issue. However, following an unconvincing performance against Norway, local reports suggest Ahmed Basil could be handed the starting role between the posts.
Striker Aymen Hussein, who previously made headlines after being detained for several hours by U.S. immigration officials, experienced a rollercoaster match against Norway.
He scored Iraq's equalizer before later putting the ball into his own net, becoming only the third player in World Cup history to score both a goal and an own goal in the same match.
