Mbappe told the French radio “Monte Carlo”: “Of course I have (self-esteem). This is important because you will not find someone to push you forward.”
“You have to always trust yourself and believe in your ability to climb mountains,” he said.
He continued, “People do not understand this idea, but when you are not in a good condition someone will not come to you and say to you: You can do this.”
“It’s about mindset, you have to believe you can do great things,” he continued.
“Every game I play I tell myself that I am the best,” he revealed.
He continued, “I played against Messi and Ronaldo and they are better than me because they won things a million times more than I did.”
He explained, “But in my head I have to tell myself that I am the best because in this way I push myself forward and cross all limits.”
“People do not understand this (self-esteem) because there is a barrier that has been created that prevents you from explaining it,” he continued.
“For people, self-esteem is not allowing your teammate to take a penalty kick or get a higher salary than the opponent’s player, but it is not like that, because it is related to preparing (for matches),” he said.
“It is a personal thing to push yourself forward. It is a far cry from saying” me, me and me, “and I think there is a lot that I can say about this.
