Mbappe endured a frustrating campaign at the European Championship, culminating in him missing the decisive spot-kick against Switzerland as Les Bleus succumbed to a shock last-16 exit.
The 22-year-old left the major tournament without a goal to his name, despite attempting 14 shots across 390 minutes of action, before returning to Paris Saint-Germain, where reports swirled of a potential move to Real Madrid.
The France international was also embroiled in a pre-tournament public war of words with fellow striker Olivier Giroud, who claimed members of Didier Deschamps' side were not passing to him before their opener against Germany.
With the poor performances and the early exit for the 2018 World Cup winners, reports emerged that Mbappe was a disruptive figure within the France setup, leading to the superstar contemplating a hiatus from the national team.
"I have always placed the French national team above everything and I will always put it above everything," Mbappe told French outlet L’Equipe ahead of the Nations League semi-final against Belgium.
"I have never taken a single Euro to play for the French national team and I will always play for my national team for free.
"Above all, I never wanted to be a problem. But from the moment where I felt like that I was starting to become a problem and that people felt I was a problem - the most important thing is the French national team.
"And if the French national team is happier without me... that is what I was made to feel and that is what I felt.
"I received the message, that my ego was what made us lose, that I wanted to take up too much space, and that without me, therefore, we might have won.
"I met with the [FFF] president, [Noel] Le Graet, and we had exchanges."
Deschamps' world champions seemingly had their Euro 2020 quarter-final berth in their grasp, leading 3-1 with just over 10 minutes remaining.
However, two late goals for Switzerland marked a remarkable comeback, which peaked when Yann Sommer guessed the right way against Mbappe in the shoot-out.
Along with the failure from 12 yards, Mbappe did not muster a shot on target despite firing in six attempts against Vladimir Petkovic's side but the barrage of abuse, including racist comments, is what left the former Monaco forward considering his future.
"I have so much love for the French national team that I abstract from it all," he continued. "What shocked me, again, was being called a monkey for the penalty.
"That is what I wanted support around, not because I took my penalty to the left and Sommer stopped it: that is on me, that is my foot that did that.
"I was booed in all of the stadiums in France! Aside from that, there was not just that, there was also the transfer, but the reality is that I was booed in all the stadiums, yes.
"But I understand everything around the sporting world now: if you are not good, you accept what people say, there you go.
"You just have to look at yourself in the mirror: I was not as good as I should have been, I accept it, and I live with this failure because it will serve me well."
