I've been covering Kylian and his career since he was like 11 or 12 years old. I still remember the first time one of my friends in Paris said, “Listen, we have this kid who is destroying everything in Paris at grassroots level, we should go and watch.” Paris is big, but it's also quite a small football world where everybody knows each other, especially at grassroots level when you're that age.
So we went to see Kylian Mbappe – future France captain and Real Madrid star – play for Bondy at a time when his shirt was too big for him, and he was already playing two years up. He was tiny and skinny, and he just destroyed the opposition, really. Since then, I kept an eye on him when he went to Clairefontaine and Monaco, obviously in the youth team, but then when he made his debut, it made sense to share it with people, to write the biography and tell the story.
