Camavinga misses out
Real Madrid midfielder Eduardo Camavinga was one of the notable absences from the squad.
He featured at the 2022 World Cup in Qatar, just over two years after becoming the second youngest player to make his debut for the French national teamat the age of17 years and 303 days.
"It's a tough situation," said Deschamps. "Eduardois coming off a difficult season in Spain where he didn't get much playing time.
"He's also had some injuries. It's true that he became part of the France team very early but he's still a young player. But I understand and I can imagine how hugely disappointed he must be."
Victory as player and coach
In July 1998, Deschamps skippered France to its firstWorld Cupcrown following a 3-0 defeat of Brazil in the final at the Stade de France in Saint-Denis.
Twenty years later at the Luzhniki Stadium in Moscow, his France team beat Croatia 4-2 to enable him to join the Brazilian Mario Zagallo and Germany's Franz Beckenbauer as the only men to lift the World Cup as a player and as a coach.
"Ive had the privilege and the immense pride of winning the World Cup trophy twice," said Deschamps.
"So those are magical moments," added the 57-year-old. "Youre on top of the world.Its always hard to fully realise it in the heat of the moment, but theres nothing stronger than that.
"I had the privilege of serving the French national team for 11 years as a player, 14 years as a coach that's 25 years professionally. Its the best thing thats ever happened to me, and to have experienced such moments is wonderful."
And then there were 48 ... how the World Cup has expanded since 1930
France kick off their Group I campaign on 16 June against Senegal at the MetLife Stadium in East Rutherford, New Jersey.
On 22 June,they face Iraq at the Lincoln Financial Field in Philadelphia and they finish the group stages with a match against Norway at the Gillette Stadium in Foxborough, Massachusetts.
In the first tournament to feature 48 teams, the top two from the 12 groups of four sides advance automatically to the last-32 knockout stages along with the eight best third-placed teams. The final will be played on 19 July at theMetLife Stadium.
Just before Deschamps outlined his choices, Fifa, which organises the World Cup, announced that the usual 15-minute pause between the two halves of the regulation 90 minutes would be extended to allow a half-time musical show for the first time at a World Cup final.
Madonna, Shakira and the K-pop band BTS will perform, said Fifa.
