Why is majority of the France National football team blacks?

I already responded soon after the last match that what matters is that they are all French. We do not do any statistic about races in France, it is strictly forbidden by our laws, we know only citizenship and we have "equality" written on our motto. But here is the official photo of the 2018 French team, you should perhaps count again.

Does it matter? If racism is to be abolished, people need to stop noticing and pointing out these "insignificant details." Teamwork is what made them winners, not the color of their skin or their cultural backgrounds.
