The Dutchman left his role at Bayer Leverkusen in March and replaced Rudi Garcia as the Lyon boss on Sunday.
Missing out on Champions League qualification, Lyon finished fourth last season, two points behind third-placed Monaco as the former Ajax and Borussia Dortmund boss is eager to make his mark at Parc Olympique Lyonnais.
"I am very happy to be here, in a great club," he said at a news conference on Sunday.
"I have a philosophy: to produce attacking and attractive football, because we play for the supporters, not for ourselves. But obviously, it depends on the players in the squad. I prefer technical and intelligent players."
Reaching the Europa League final in 2017 with Ajax, the Dutchman is eager to put his focus as Lyon youngsters as he believes the same approach as Ajax would benefit his side.
"At Ajax, like at Lyon now, it was important to play the youngsters," he said. "But it does not just depend on the age: I am not scared to give young players a chance and to put faith in them. They have the qualities. At Leverkusen for example, I gave Florian Wirtz a chance when he was just 16.
"In the Netherlands, it was said that the team started seasons slowly and finished strongly. In Germany, I was told that the team started strongly and finished slowly. What I want, in France, is to start and finish strongly.
"I am heading back for two more weeks of holiday, but I will of course remain in contact with Juninho to talk about the players, pre-season, the way of working. I will be thinking a lot about Lyon."
