At just 23 years old, Ferdinand had his whole career ahead of him, but even he wouldn't have been able to believe all the things he would go on to achieve.
Six league titles, one Champions League, one FA Cup, two League Cups and one World Club Cup is a pretty respectable tally of medals. Furthermore, only five players have won the Premier League more times than him.
Whilst there have been many highs during his 12 seasons at United, there have also been a few lows, with Ferdinand not a unanimously popular player amongst supporters. However, that doesn't change the strong feeling he has for the club.
"I'll be a United supporter for the rest of my life, so will my kids," Ferdinand told The Republik of Mancunia last month. "It’s in me now, so I can't get rid of it!"
