Over the course of 27 years, Sir Alex Ferguson built a dynasty at Manchester United.
While he was renowned for giving youth players their chance to shine at Old Trafford, Ferguson was not averse to splashing the cash when it came to adding integral components to his time.
During his time at Manchester United, Ferguson broke the British transfer record on three separate occasions, with the £7million signing of Andrew Cole in January 1995 sending shockwaves across the football world.
The most expensive signing Sir Alex made during his time at the club came a full decade before he finally stepped away from the club.
Just one year after he made Juan Sebastian Veron the most expensive player in British football history, Ferguson again spent big the following summer to sign Rio Ferdinand from Leeds United.
The deal, worth an initial £29.3million, made Ferdinand the most expensive defender ever for the second time in his career.
Ferdinand would more than repay the faith Ferguson had showed in him during his 12-year stint at United, winning six Premier League titles and the UEFA Champions League in 2008.
But who else joins Ferdinand in the list of Sir Alex's biggest signings? Read on to find out.
