Sir Alex Ferguson made incredibly savvy signatures during his reign as Manchester United boss, which helped them dominate during the Premier League era.
Players like Eric Cantona, Roy Keane, Cristiano Ronaldo and Wayne Rooney have turned into club legends for relatively modest transfer fees.
With their revered academy products, Ferguson has won 13 championship titles and countless other national trophies.
Man United was often linked to some of the best players in the world and the best XI of players they have almost signed is incredible.
However, not everything that Fergie did turned into gold, as there were also some really shocking transfers among the excellent ones.
Here, talkSPORT.com, look at the worst XI of players signed by the big manager.
Goalkeeper: Massimo Taibi
Taibi had the unenviable task of filling the boots of a certain Peter Schmeichel and was a complete disaster.
He was signed for £ 4.5 million in 1999 and has only played four games with Man United.
This included five goals against Chelsea and the famous goal left in Southampton when a tame stroke from Matt LeTissier crossed his legs.
Left back: Quinton Fortune
Fortune was signed for £ 1.5 million in 1999 from Atletico Madrid and first came to the club as a midfielder.
Ferguson used it in the back left but was often disappointing when he was playing. He participated in three seasons of Premier League victory but did not play enough games to win a medal.
He was released by the club at the end of the 2006/07 season.
Central defender: William Prunier
Prunier was signed on a trial basis in 1995 while United was ravaged by injuries. He linked Gary Neville to the heart of the defense against QPR, then Tottenham, who rioted for four goals.
He was released soon after and ended up in Copenhagen.
Central defender: Pat McGibbon
Ferguson signed McGibbon on the semi-professional Irish side of Portadown in 1992. He was kicked out when he made a 3-0 loss to York in the League Cup and has never made another appearance for the club despite his stay for five years.
Right-back: David May
May was signed as central defender in 1994 for £ 1.2 million from Blackburn to compete against the aging Steve Bruce and Gary Pallister.
Paul Parker’s injuries forced him to play in the right back and was often the scapegoat for United’s poor performance.
However, the rise of Gary Neville also meant that time in the back right was limited, although it was immortalized in the 1999 Champions League triumph.
He is popular with United fans for his work behind the scenes and on club podcasts.
Left midfielder: Zoran Tosic
The sly winger was signed by Partizan, with teammate Adem Ljajic, in January 2009 for around £ 7 million.
In 12 months, he made only two appearances before growing impatient and wanted to leave the club.
It was then loaned to Cologne and sealed a permanent move to CSKA Moscow.
Central environment: Bebe
You could say that the strangest and worst signature was made during the Ferguson era at United.
He was signed for £ 7 million, Fergie admitting never having seen him play.
Bebe was terrible and made seven appearances in its first season before being shipped on loan before it could be unloaded at Benfica in 2014.
Central environment: Kleberson
Kleberson helped Brazil win the World Cup in 2002 and Luiz Felipe Scolari hailed him as the engine of their success.
United got their signature 12 months later by paying a whopping £ 6.5 million. It was a disaster, however, and only made 20 appearances before being sold to Besiktas two years later.
Right midfielder: Karel Poborsky
Poborsky was named to the Euro 1996 tournament team and won the title of Czech footballer of the year when transferred to United.
He was somewhat overshadowed by David Beckham and never showed his full potential at Old Trafford before leaving for Benfica 18 months later.
Forward: David Bellion
United was charged with retaining Bellion in 2003 after its contract expired in Sunderland. This resulted in a payment of £ 2 million in compensation and it is disconcerting why they made so much effort to sign the striker.
He left definitively in 2006 after having failed to make a strong impression.
Forward: Dong Fangzhou
The striker was signed for £ 500,000 from the Chinese side of Dalian Shide in 2004. He failed to score during his time at Old Trafford and was released four years later.
It was suspected that it had been signed to help increase the popularity of the Red Devils in China and the rest of Asia.
