Robert Lewandowski's Chicago Fire jersey has become the top-selling item in Major League Soccer since his June arrival, remarkably outselling Lionel Messi during this period. While Messi, who joined Inter Miami in 2023, still leads the full-year sales list for the fourth consecutive season, Lewandowski's impact is significant. The former Barcelona and Bayern Munich striker signed on June 29 and debuted on July 22, contributing seven goals and five assists in 18 games, helping the Fire secure a playoff spot and fourth place in the Eastern Conference. Other top sellers include Son Heung-min (LAFC), Thomas Müller (Vancouver), Antoine Griezmann (Orlando City), and Cavan Sullivan (Philadelphia). Sullivan, a 17-year-old, is set to join Manchester City in January 2028, representing a promising homegrown talent amidst the league's reliance on established global stars.
