Major League Soccer is seeking to sustain the attention generated by North America’s World Cup hosting, but the article argues that signing celebrated older players such as Casemiro will not be sufficient on its own. The Brazilian midfielder has joined Inter Miami after leaving Manchester United, while promising homegrown player Sebastian Berhalter has moved from Vancouver Whitecaps to Middlesbrough, highlighting MLS’s difficulty in retaining young talent.

Casemiro, 34, was unveiled by Inter Miami as a five-time Champions League winner, former Brazil captain and 91-cap international, saying he wants to help develop both the club and MLS. His arrival follows other high-profile veteran signings including Antoine Griezmann, Robert Lewandowski, Son Heung-min and Timo Werner, while Miami already features Lionel Messi and several former Barcelona stars. The article contends that these names sustain interest, but MLS needs to persuade America’s best young players to remain if it is to build a lasting legacy.
