Debate has raged over whether Pogba merits a place in midfield, with the Manchester United man failing to convince in recent matches.
He was jeered by his own fans during the 3-1 friendly win over Italy and failed to inspire France in an underwhelming 1-1 draw against a youthful United States on Saturday.
Deschamps, however, is continuing to back the 25-year-old, telling broadcaster Telefoot it is "very likely" he will be in the starting XI in Kazan on June 16.
The boss of Les Bleus also offered assurances over the fitness of Giroud, who was bloodied and forced off following a head clash with USA defender Matt Miazga.
"Olivier Giroud has a beautiful cut of 6 centimeters. But he will be able to face Australia," Deschamps said.
