Manchester United have attracted some of the best players in the world to Old Trafford throughout their history.
The club has a track record of producing their own players, but they haven't been shy about splashing the cash to bring in some of the finest players from around the world.
Some of United's foreign imports have been flops like Cameroon midfielder Eric Djemba-Djemba or Portugal winger Bebe.
But some have gone on to change the course of United's history like Eric Cantona and Cristiano Ronaldo.
Here's a list of the 30 best foreign imports to grace Old Trafford, with weight given to how much they cost, what they achieved and how popular they were during their stay.
There were plenty of players who didn't make the cut so feel free to use the comments section below to add your own list.
Juan Sebastian Veron was signed for a club-record £28.1million when he arrived at United from Lazio in 2001, but his two seasons at Old Trafford are usually remembered as a disappointment.
Sir Alex Ferguson often struggled to accommodate the Argentinian in a midfield which also included Roy Keane, Paul Scholes and occasionally Nicky Butt.
He was allowed to depart for Chelsea in 2003 after scoring 11 goals in 82 games for United, but that hasn't stopped him from remaining a fans' favourite.
Fabien Barthez replaced Mark Bosnich as United's No. 1 when he was signed from Monaco in the summer of 2000.
He arrived at Old Trafford a World Cup and European Championship winner with France, but he was often as error-prone as he was flamboyant.
He won the Premier League title in 2001 and 2003 before leaving for Marseille after playing 139 games for United.
Henning Berg cost £5million when he joined United from Blackburn in 1997.
The Norwegian defender was never a regular starter at Old Trafford after facing competition from Ronny Johnsen and Jaap Stam during his three full seasons at Old Trafford.
Injury robbed him of a place in the squad for the 1999 Champions League final, and he rejoined Blackburn in 2000 after making 103 appearances.
Juan Mata might have only just arrived at United, but he does so with a fearsome reputation.
He's a World Cup and European Championship winner with Spain and has won Chelsea's Player of the Year award in both of his two seasons at Stamford Bridge.
His task now, after becoming United's record signing last month, is to lead the club into a new era under David Moyes.
There were plenty of people who said United had only signed Park Ji-Sung to sell a few shirts in South Korea when he arrived from PSV Eindhoven in 2005.
He was unspectacular—but incredibly hard-working—and had more than justified his £4 million fee by the time he left for QPR in 2012.
It is unfortunate that his last game in a United shirt was a miserable night against Manchester City at the Etihad Stadium when the 2012 title began to slip away.
It was a disappointing end to what had been an impressive seven years at Old Trafford.
Adnan Januzaj is another whose career at United is only just starting, but what a start it has been.
The Belgian-born midfielder has been thrust into the first team as a teenager this season, and, despite a difficult transition under new manager David Moyes, he's been one of United's standout performers.
Few supporters will forgive Carlos Tevez for moving across Manchester to sign for Manchester City in 2007, but it shouldn't take away from what he helped United achieve in his two seasons at Old Trafford.
Signed from West Ham in 2007, the Argentinian striker was part of the team that won the Champions League in 2008 with a penalty shootout victory over Chelsea in Moscow.
He left with two Premier League titles after scoring 34 goals in 99 games.
Since arriving from Brazil with his twin brother Fabio in 2008, Rafael da Silva has matured into one of the finest right-backs in the Premier League.

David De Gea overcame the problems he had settling into life in the Premier League to be named England's best goalkeeper last season.
The Spanish keeper arrived from Atletico Madrid for nearly £19 million in 2011 to fill the sizeable gloves of Edwin van der Sar, and it's proved to be a sound investment.
Still only 23, he could have another 10 years as United's first-choice No. 1.
History will probably remember Dimitar Berbatov as a flop after Sir Alex Ferguson paid a club-record £30.75 million to sign him from Tottenham in 2008.
But it should be remembered that he finished as the Premier League's top scorer in 2011, goals that ultimately helped United win the title.

Gabriel Heinze is another whose time at United is remembered for how he left rather than what he did on the pitch.

The Trinidad and Tobago forward was only at Old Trafford for four seasons before leaving for Blackburn in 2002.
Andrei Kanchelskis' legacy at United is tainted by the way he tried to force a move to Everton in 1995, but he was a wonderful player when he was at his best.
Signed for just £650,000 from Shakhtar Donetsk in 1991, he scored 29 goals in 161 games.
He left in 1995, along with Paul Ince and Mark Hughes, but it was the flying Ukrainian winger whom United missed the most.

And his 25 league goals in 2002/03 helped United lift the Premier League title.
It wasn't until Edwin van der Sar arrived from Fulham in 2005 that Sir Alex Ferguson found a long-term and reliable replacement for Peter Schmeichel.
