The Arsenal midfielder picked up an injury in their 2-1 defeat to Chelsea last weekend and the French coach then pleaded for him to remain with his club during the international break.
Deschamps was not impressed with Wenger's demands - though Diaby was not included in his party - and sent out a defiant warning to the veteran Premier League manager.
"I want to remind him that I am the only one to decide who will be picked and how long those who are picked will play," Les Bleus' coach told reporters on Thursday afternoon.
"There is only one to decide and it's me."
Although Manchester City playmaker Samir Nasri's three-game international suspension has been served, Deschamps has opted not to give him a recall for their friendly against Japan on October 12 and their World Cup qualifier in Spain on October 16.
"I didn't think it was the right time to call him back, I prefer to wait a while," he added.
Les Bleus' battle against Spain could be crucial in deciding the composition of Group I, with only one nation qualifying automatically for World Cup 2014.
That will leave the second-placed side having to go through the play-off process and Deschamps is realistic about the challenge ahead.
"Maybe they are missing some players, but they are still the best team in the world," he commented.
"The facts are there. No other team has won the European Championship, the World Cup and the Euros again."
