The French superstar has started his second campaign with Los Blancos in impressive form and believes that he is fully settled in at the La Liga club following his high-profile switch from PSG in 2024.
Mbappe said: "I've adapted well to Madrid, I'm a little more relaxed there.
"This isn't an attack on France. The lifestyle is different, it's less hectic than in Paris. I've managed to get my head and legs back in place."
The forward will be in action for France in their World Cup qualifier against Azerbaijan on Friday (10.10.25) but is not taking the minnows lightly - even though the game gives him a chance to close in on Olivier Giroud's 57-goal record for the national team.
Mbappe, who has netted 52 times for his country, said: "I think I'm going to break the record. When, I don't know, I don't think about it.
"Maybe tomorrow, maybe in a long time. The most important thing is to qualify for the World Cup. That will come naturally.
"I'll be happy when it happens and I'll move on because there's something to be done.
"But this is a team [Azerbaijan] that held Ukraine to a draw so we cannot mess around.
"The stakes are higher than scoring goals, even if we're not going to hold back."
France coach Didier Deschamps echoed Mbappe's thoughts about taking the challenge posed by Azerbaijan seriously.
He said: "We respect all our opponents. They have that national fervour too and given their last result they have nothing to lose.
"We mustn't give them the opportunity to have dangerous situations against us.
"It's not always easy as a player. Just because we have six points doesn't mean we're already qualified.
"We can tease or mock Italy [who missed the last World Cup] but we mustn't have a short memory because we've been through that too.
"In football, it doesn't take much, I don't want to leave room for chance or imponderables."
