BERLIN—It was the perfect location: a large arena with space for up to 17,000 spectators, in the middle of Berlin, practically opposite one of Germany's most famous landmarks, the Berlin Wall. Within a kilometre of the Uber Square that surrounds the stadium, everything pointed to one topic: tennis.
For the first time ever, the Laver Cup was coming to Germany, and every Berliner was supposed to know about it. All around the area, there were advertising banners, large posters and pictures of tennis players like Carlos Alcaraz, Alexander Zverev or Roger Federer, all of whom were in the city.
