Kakuta, who will turn 35 during next month’s finals in Canada, Mexico and the USA, has played only twice in the last two years for the Congolese, brought in as an injury replacement at the Africa Cup of Nations finals in Morocco at the turn of the year.
But he was left out in March, when the Congolese became the 10th African country to qualify for the 2026 finals by beating Jamaica in an inter-confederation playoff in Mexico, which suggested his international career might be over.
Kakuta is a former Chelsea prodigy, whose signing as a teenager from France was mired in controversy but who never made the expected breakthrough at Stamford Bridge and has since played for 15 clubs in nine different countries.
For the rest, Desabre stuck with the side that finished fourth at the 2023 Cup of Nations and reached the last 16 in Morocco.
"The squad has picked itself because we’ve all been together now for some four years. The World Cup is no forum for experimenting or development," he said on Monday.
D.R. Congo will compete in Group K at the finals, where they take on Portugal, Colombia and Uzbekistan.
"We want to play to our best level, and our objective is to get past the first phase, which I believe is well within our capacity," Desabre added.
The country was known as Zaire when they last played at the World Cup in West Germany in 1974, losing all three games, including a 9-0 defeat to Yugoslavia.
