The 57-year-old coach - whose 14-year stint in charge of France is due to end after the World Cup - insisted he doesn't always take the same approach to his players and the side's tactics, but he won't make changes just "for the sake" of it.
He told The Guadian newspaper: “I have a magic word: adaptation … I say to myself, ‘In relation to the person I have in front of me, I adapt.’ And so it leads to modifications …
"It’s not because we did this and it worked well that we shouldn’t change. It’s not about changing for the sake of changing either.
“The generation from when I started in 2012 is not the same as today … the new generation need more exchanges."
Didier will have to make decisions on who plays up front for France, with captain Kylian Mbappe set to line up alongside the likes of Michael Olise, Ousmane Dembélé, Rayan Cherki, Désiré Doué, Bradley Barcola, Marcus Thuram, Jean-Philippe Mateta and Maghnes Akliouche.
He reflected: “It’s about managing the frustration of those who won’t start the game.
“It’s always hard to accept, because each player thinks he’s better than the one who plays in his place … ask any professional footballer at the very highest level, they will say: ‘Competition? Well, of course, it’s part of our life,’ but only when it concerns a teammate, when it concerns them it’s more difficult.”
The manager faced criticism for choosing Mbappe to succeed Hugo Lloris as captain, but he believes he made the right decision.
He said: “Kylian, today, who is our captain, before being captain, he listened, he looked, he doesn’t do things like Hugo. It’s not at all the same character and personality.
"He takes on this leadership outside, on the pitch as well, and he knows that when he speaks, he doesn’t speak in his own name, but he speaks in the name of all the players as well.
“I must be stupid, and there must have been a lot of stupid people who he has had as coaches to put him in the middle of the attack within the teams he has played … for the past two years at Real and his last year at PSG … it’s been three years that he has played in a central position.”
