Iconic Global Superstar David Beckham had a wonderful career playing for Man Utd, Real Madrid, AC Milan and PSG etc. Not many can boast this, especially the longevity of service under all these clubs! Even if we did replace him with the world's best footballer CR7. Weighting up him as a brand, the attention that came with it and his talent on the pitch. Did Sir Alex Ferguson make a mistake selling David Beckham???
