Robert Lewandowski's impact on Major League Soccer has been significant since his arrival to the league in June. The Poland international has recorded seven goals and five assists in 18 games, propelling the Chicago Fire to fourth place in the Eastern Conference table and a spot in the playoffs. His jersey has been the most popular in MLS since his debut, outselling even Lionel Messi's Inter Miami kit. Messi, however, still leads sales overall, earning first place for the fourth consecutive season. The list was based on sales made on MLS' online store from January 1 to October 30. Other notable players on the list include Son Heung-Min of LAFC in second place and Thomas Müller of Vancouver Whitecaps in third. The list highlights the popularity of new signings and rising stars in the league.
