Sports figure(s) involved: John Harkes and Eric Wynalda
Just two months before the 1998 World Cup, U.S. soccer coach Steve Sampson dropped John Harkes, the team's captain and one of its best players, for "leadership issues." The coach stayed quiet about the details for almost a decade, but later revealed in an interview that it was because Harkes was having an affair with Amy Wynalda, the wife of teammate Eric Wynalda. In case you're wondering, Sampson found out about the affair because another teammate, Roy Wegerle, spilled the beans like a gossiping teenager. SMH. For all of its drama, the team didn't win a single game and had perhaps the most disappointing World Cup performance in the field.
