10. Gabriel Heinze
Gabriel Heinze isn't the most popular of United's former players. But there was a time when he was a fans' favourite.
He arrived from Paris Saint-Germain for £6.9 million in 2004 and spent three years as the first-choice left-back.
9. Carlos Tevez
Carlos Tevez is another former player who isn't particularly welcome at Old Trafford.
But his two seasons at United were very successful. He scored 34 goals in 99 games, winning two Premier League titles, the League Cup and the Champions League.
But that was all quickly forgotten when the Argentinian striker moved to Manchester City in 2009.
8. David De Gea
It was a gamble for Sir Alex Ferguson to pay £17.8 million for a goalkeeper who was barely out of his teens in 2011.
And after a shaky start to the Spaniard's United career, he's become one of the best goalkeepers in the Premier League.
Still only 23 years old, he's got time to get even better. And make that £17.8 million look even more of a bargain.
7. Michael Carrick
Michael Carrick moved to United from Tottenham for £18.6 million in 2006.
And the England midfielder has enjoyed incredible success at Old Trafford.
In eight seasons he's played more than 350 games, won five Premier League titles, the League Cup, the Club World Cup, reached three Champions League finals, winning one.
Now 33, he's held together United's midfield, sometimes single-handedly, for nearly a decade.
6. Ruud Van Nistelrooy
Ruud van Nistelrooy left Untied under a cloud in 2006 after falling out with Sir Alex Ferguson.
But in just five seasons, he cemented his place as one of the club's greatest goalscorers.
United paid £18.5 million for the Dutchman in 2001 and he went on to score 150 goals in 219 games.
He won the Premier League title in 2003 and the FA Cup in 2004 before leaving for Real Madrid in 2006.
5. Robin Van Persie
Robin van Persie has only been at United for two years. But many fans would argue he paid back his £24 million fee in his first season.
He scored 30 goals in 48 games in his first year after arriving from Arsenal in 2012.
His goals helped United wrestle the Premier League title back from Manchester City, who had won it in dramatic fashion a year earlier.
4. Edwin Van Der Sar
Edwin van der Sar will go down as one of Sir Alex Ferguson's most impressive transfer coups.
The Dutchman signed for United in 2005 for just £2 million. He went on to play until he was 40, playing 266 games, winning four Premier League titles and two League Cups.
He also saved the crucial penalty in the 2008 Champions League final against Chelsea as United won the shootout in Moscow.
3. Rio Ferdinand
United made Rio Ferdinand the world's most expensive defender and the most expensive British footballer when they paid Leeds £29 million in 2002.
And despite the huge fee, there aren't many United fans who don't believe they got value for money.
Ferdinand left at the end of the season—his 12th at Old Trafford—having played 455 games, winning six Premier League titles and the 2008 Champions League.
2. Wayne Rooney
Wayne Rooney's United career looks set to end with the England striker sat on top of the club's goalscoring charts.
Still only 28 years old, and with a new five-year contract in his pocket, he needs only to pass Denis Law and Sir Bobby Charlton to do it.
Rooney was the world's most expensive teenager when Sir Alex Ferguson paid Everton £25.6 million in 2004.
He's gone on to win five Premier League titles and the Champions League. He's also been named the new club captain, succeeding Nemanja Vidic.
1. Cristiano Ronaldo
Cristiano Ronaldo arrived at Old Trafford from Sporting Lisbon as a scrawny teenager in 2003. He left in 2009 as the world's best player.
Sir Alex Ferguson paid just £12.6 million for the winger in 2003. He was sold to Real Madrid six years later for a world-record £80 million fee.
He scored 118 goals in 292 games at United. He won three Premier League titles and was the star in the team that reached three Champions League finals in four years between 2008 and 2011.
