David Beckham believes Lionel Messi will need time to adapt to Major League Soccer, even though the standard of play is at a "different level" from the European game. Inter Miami co-owner Beckham, the former Manchester United and Real Madrid midfielder, watched Messi take part in his first training session for the club on Tuesday after signing a two and a half year contract. Spanish midfielder Sergio Busquets, a former team-mate of Messi's from Barcelona, also trained at the club's complex, after signing on Saturday, with former Barcelona and Argentina coach Gerardo 'Tata' Martino leading the session.
