How 'Posh and Becks' spelled the end for 'The Boss' and Becks: Ryan Giggs claimed Sir Alex Ferguson HAD to sell David Beckham because they 'were arguing every other week'... and marrying a Spice Girl led to THAT flying boot and an emotional break-up

For a manager who never hid the need for control, Sir Alex Ferguson's relationship with David Beckham - the world's most famous and powerful player - was always liable to have tensions.

By the time Golden Balls left to become a Galactico at Real Madrid in 2003, Manchester United simply wasn't big enough for the both of them.

That evocative nickname for Beckham was coined by his wife Victoria in 2001. As a Spice Girl, she was as famous as Fergie or her husband during that period and an important influence in the breakdown between manager and glamour star.
