Ask any Manchester United fan, Rio Ferdinand is a club legend.
The centre-back was undoubtedly one of the most talented defenders of his generation and his transfer remains one the club's best pieces of business in decades. But the controversial switch from Leeds United was not an easy one to push through.
With the two clubs sharing a bitter rivalry across the years, the Elland Road outfit were initially uneasy about negotiating with United for the former West Ham defender. Then-Leeds chairman Peter Ridsdale dug his heels in and played hardball and at times it looked as though United would miss out on the talented centre-back.
