After almost 4½ months, football was played again in France on Friday, and in front of fans as well. Yet, instead of celebrating the return of the nation's favourite sport with the Coupe de France final between Paris Saint-Germain and Saint-Etienne, instead of celebrating being the first major European nation to safely welcome supporters (with French president Emmanuel Macron among the 5,000-strong crowd), instead of celebrating another trophy for PSG to go with this season's league title after their 1-0 win, what everybody is talking about is the injury to Kylian Mbappe.
