David Beckham

David Beckham – is there a more famous and lovable celebrity? The footballer who played for such famous teams as Manchester United and Real Madrid is also a fashion model and a successful businessman.

David Beckham was born on May 2, 1975, in London, England. His father Ted Beckham was a kitchen fitter and his mother Sandra, a hair stylist. David Beckham was the family's only son. A middle child between two sisters, David grew up with parents and relatives who were great fans of Manchester United, England's legendary football club. From childhood, David was a promising footballer. At 11 he won the prestigious Bobby Charlton Soccer Schools National Skills Competition. David was noticed by Manchester United team officials, who asked him to try out for the club's youth league. By the age of 16, Beckham had to drop out of school. He left home to play for his favourite team. Two years later he became a full-time player for Manchester United and one of its leading figures.

From 1992 to 2003, playing for Manchester United, David Beckham scored 85 goals. Every time he had a game, he wore different football boots – it was a sort of ritual for good luck. In 2003, David unexpectedly left his beloved team for Real Madrid. The reason was the growing conflict between David Beckham and Manchester's manager, Sir Alex Ferguson. Once Sir Alex Ferguson fined David for babysitting with his sick child, while his wife Victoria, a designer, was at a London Fashion Week Event. The fine was really large. The incident caused a serious personal tension between the two men and ended in Beckham moving to the other club.

In Real Madrid, David Beckham was not allowed to wear his favourite number seven, because the right to wear it was written into the contract of another player. Instead, David decided to wear a shirt with number 23, which was the number of his favourite basketball player Michael Jordan. Though David Beckham immediately became very popular with the Real Madrid fans and his shirt sales made a lot of money for the football club, the team didn’t win any serious tournaments. Perhaps, it was one of the reasons why in 2007 Beckham signed a five-year contract to play for the Los Angeles Galaxy and moved to America. However, his career in America was a rocky one – numerous injuries affected him. In May 2013, David Beckham announced his plans to retire.

It’s important to say that David Beckham has always been a devoted husband and a loving father. David and his wife Victoria have three sons and a daughter. They say the boys are being trained as ‘bodyguards’ for their little sister Harper. The youngest, Cruz, has been practicing Taekwondo, Brooklyn is interested in boxing, and the oldest, Romeo, does karate. They are preparing early so that when Harper is older, “they will all be ready to protect her from noisy fans,” David says.
