An own goal, a controversial Antoine Griezmann penalty and memorable goals from Paul Pogba and Kylian Mbappe earned Les Bleus their second World Cup triumph.
Speaking to a news conference after the game, and quoted by Reuters, Deschamps was particularly keen to highlight his young side's mental attitude. "It’s a young team who are on the top of the world," he said, adding: "Some are champions at the age of 19, but my greatest source of pride is they had the right state of mind."
Nevertheless, even while lauding his players, Deschamps acknowledged that his side hadn't given an impeccable performance, saying: "Today we did not do everything right but have those mental and psychological qualities which were decisive - and we did score four goals."
France were outplayed for long periods by an impressive Croatia side, but their star trio of Griezmann, Pogba and Mbappe all made match winning contributions when needed.
The result means that Deschamps is now just the third man in history to win the World Cup both as a player and as a manager, after Brazil's Mario Zagallo and Germany's Franz Beckenbauer.
However, Deschamps modestly refused to focus on this aspect of his side's triumph, which came 20 years after he had lifted the trophy as France captain. "This is not about me, it’s about everyone around me and the players," he insisted.
The 49-year-old also hailed the current France side's 'beautiful' World Cup triumph, which he put on a par with the 1998 win: "I had the immense privilege to live through this 20 years ago, and in France, but what the players have just done is just as beautiful, just as powerful," he said.
