A sold-out crowd of around 20,000 waited through a delay caused by torrential rain and heavy lightning to officially welcome Lionel Messi to Inter Miami on Sunday. The club's co-owner David Beckham opened the ceremony saying Messi's arrival was a "dream come true". "Leo, we are so proud that you have chosen our club for the next stage in your career," said the former Manchester United player whose move to MLS's Los Angeles Galaxy in 2007 was the league's previous biggest arrival. "Welcome to our family Leo," Beckham added in Spanish, to roars from the crowd. Upon being introduced, Messi briefly addressed the crowd before the team played a tribute video on the scoreboard screen. The likes of Tom Brady, Stephen Curry, DJ Khaled and Gloria and Emilio Estefan welcomed Messi to the United States.
