Last weekend, near Saint-Brieuc, we could hear “Zizou, Zizou” rise again from the stands of a sports arena. Not those of a football stadium, no, those of the Steredenn room, hostess of the ATP Challenger tournament in the Costa Rican city. The Zizou in question is blond, wears the cap backwards like Andy Roddick from the US Open 2001 era, and, therefore, he plays tennis. Rather well, even if he lost in the final at the expense of the Briton and 124th in the world Jack Draper.
