It seemed to be a perfect match: France’s top soccer player agreeing to star for his hometown club. And for a while it was. Kylian Mbappé was the star attraction that France’s premier team, Paris Saint-Germain, planned to build around for years to come. Its owners, an arm of the Qatari government, brought him back to Paris from Monaco in 2017 for about $200 million, a record deal for a teenager, and at the time the second-highest fee ever in soccer. Goals were scored, trophies were secured, Mbappé became one of the most famous athletes in the world, and the bond between player and club was forged. Then came the trouble. Mbappé, now 26, had since childhood dreamed of playing for Spain’s Real Madrid — soccer royalty — and his chance came in 2022 with his contract expiring. Ultimately, he stayed put, but only after a herculean effort that involved cajoling by President Emmanuel Macron of France and what the club claims was the richest contract in European soccer.
