Beckham’s decision to retire came sooner than he imagined. He joined French Ligue 1 side Paris St-Germain in January 2013 but it was a step too far, with Beckham, now aged 38, left feeling like he “had been beaten up” after games. Beckham, now 48, came through the ranks at Manchester United under Sir Alex Ferguson and went on to become a global superstar. But the winger and his manager had a number of well-documented stormy moments – and Beckham was eventually sold to Real Madrid. Sir Alex infamously kicked a boot into Beckham’s face during one row.
