The Messi Effect: How the Global Legend Changed the Future of American Soccer

By Paul Tenorio

In The Messi Effect, Paul Tenorio, national soccer writer for The Athletic, draws on coveted insider access to bring readers behind the ropes and into the inner sanctum and chronicle the last act of Lionel Messi.

In The Messi Effect, Paul Tenorio, national soccer writer for The Athletic, who has spent more than a decade breaking news and providing critical insight into the power and politics of the sport, draws on his numerous high-ranking sources inside Inter Miami, American soccer, and overseas to bring readers behind the scenes and chronicle the last act of Lionel Messi.

The Messi Effect takes you inside the locker room as Messi's arrival turned a last-place team into a global phenomenon, and into the Major League Soccer boardroom as league owners debated how to leverage Messi's arrival to shape the future of the league and sport in America. From his cinematic debut goal to his first trophy with Miami and across two more transformative seasons, Messi's impact was immediate and enormous. His pink No. 10 shirt became the world's best-selling jersey, MLS stadiums sold out in city after city, and Inter Miami's valuation soared past $1 billion.

This is a book about one man's legacy in a rapidly growing and changing game. It's a story about the business of sport and how a player can be both athlete and economic engine. It's an inside look at how the business of MLS evolved historically and in real time after the legend's arrival. And it's the story of how a GOAT rides off into the sunset, the choices he makes, and the aftereffects of his greatness for future generations
