Manchester United have spent nearly £ 1 billion in transfers since Sir Alex Ferguson left the club at the end of the 2012-13 Premier League season.
Despite charging huge transfer fees, United slowly withdrew from the title fight, with rival Manchester City spending similar money and reaping the rewards on silverware.
Ferguson, who ran the club for 27 years, was replaced by David Moyes. Since then, United has been run by Ryan Giggs as janitor, Louis van Gaal, Jose Mourinho and current boss Ole Gunnar Solskjaer.
Here Sportsmail looks at all the signings Manchester United managers have made since Ferguson left the club …
David Moyes and a succession of managers spent large sums at Manchester United
Juan Mata (£ 37 million)
The Spaniard joined Premier League rival Chelsea in January 2014 and was the player of the year last season, but then lost the favor of Jose Mourinho, who returned for a second spell at Stamford Bridge.
Mata still regularly appears on the Manchester United side and is one of the most experienced dressing room figures.
Juan Mata has been an important part of the Manchester United team since arriving in 2014
Marouane Fellaini (£ 28 million)
The Belgian joined Manchester United on the transfer deadline in the summer of 2013, following Moyes from Goodison Park.
He failed to impact Moyes and the managers who followed him and quickly became an impact substitute rather than a novice.
He was responsible for some of United's greatest moments after Fergie. More successful than most.
Louis van gaal
Angel di Maria (£ 59.7 million)
The Argentine joined Real Madrid with great fanfare and the rate was the highest ever paid by a British club at the time.
It is safe to say that his time in Manchester was not the best, with only four goals in all competitions. He never truly settled in England after suffering the shock of being home with his family when thieves tried to break into his property. Since then, he has revived his career and is an integral part of the PSG team.

Anthony Martial (£ 36 million)
The Frenchman joined United in a deadline dispute for an attacker and the additions meant the rate could rise to £ 58 million if certain conditions were met. There was a lot of pressure on Martial, who hit the ground running with three goals in the first two games.
His time at the club had frustrating spells; getting behind Zlatan Ibrahimovic and Marcus Rashford under Mourinho. But when fit, it now appears to be an important part of Solskjaer's plans in the future.
Morgan Schneiderlin (£ 31 million)
Another player from the Van Gaal era that had a significant impact but did not. Hired at Southampton, the central midfielder was one of the best prospects in the Premier League but failed to prove his worth in the red of Manchester United.
Since then, the 29-year-old has left the club for Everton, where he is still trying to rediscover the form in Southampton days.
Morgan Schneiderlin made no impact on United and has since moved to Everton
Luke Shaw (£ 30 million)
Shaw struggled to settle at Manchester United due to injury problems in the first two seasons. He looked destined for the door after losing his spot alongside Daley Blind and Marcus Rojo, but changed things last season to win the club's Player of the Year award.
Shaw still has a lot of potential and has shown a great character to return to the team.
TRUTH: JURY'S OUT
Ander Herrera (£ 28 million)
This was a hotly contested transfer saga to United after several bids rejected by Athletic Bilbao under Moyes.
Herrera added energy in midfield and was an effective defensive screen in front of the four defenders. In the summer, he left and joined PSG on a free transfer, leaving many Manchester United fans frustrated.
Ander Herrera had a positive impact on Manchester during his five-season stay at the club.
Memphis Depay (£ 25 million)
The Dutchman could not find his feet in England with just seven goals in 53 matches. He left for Lyon, where he became one of the most dangerous strikers in European football.
Since leaving, Depay has been honest about his short time at United: “I have no bitterness for Mourinho. I don't think I was good enough for him.
Marcos Rojo (16 million pounds)
After reaching the 2014 World Cup final with Argentina, Rojo was on the watch list of many clubs, but it was Van Gaal who hired the defender.
He joined a five-year contract and entered the field and could play for the left back or defender. Since then, he has become a lackluster figure in the current cast and fans don't know if he's good enough.
TRUTH: JURY'S OUT
Marcos Rojo has been an indifferent signing for United but still has a chance to improve
Daley Blind (£ 13.8 million)
Blind joined the club, having previously worked with Van Gaal for the Netherlands team.
Although he never lit the world, he was a solid player during his time at Old Trafford, but got lost a bit in the Mourinho era and now plays for Ajax. In today's market, £ 13.8 million seems more than reasonable for its contribution.
Matteo Darmian (£ 12.7 million)
Darmian was an exciting acquisition when he was hired by Torino on a four-year contract. He had the perfect opportunity to become a regular player, with Ashley Young and Antonio Valencia entering the twilight of their careers.
Unfortunately, he often looked deeply and returned to Italy with Parma in the summer.
Matteo Darmian took no chances and is now becoming an outcast at the club
Bastian Schweinsteiger (6.5 million pounds)
At just 6.5 million pounds, the German seemed like a fantastic deal. Of course he wasn't young, but he had an unrivaled experience of anchoring the Bayern Munich midfield in countless trophies.
He showed glimpses of his ability, but too often deflected United's pace and quickly descended as he was relegated to the under-23 team before being sent to MLS by Chicago Fire.
Radamel Falcao (£ 6 million, borrowed)
Falcao joined Manchester United as one of the most famous and feared strikers in the world and left a failure.
United fans believed Falcao would lead the attack that could win another Premier League title, but that was not the case. The Colombian scored just four goals before lending to Chelsea, where he also failed to impress.

Sergio Romero (Free Download)
Romero has signed a contract for the club to play against David De Gea, however, has seen more than planned at times.
The goalkeeper has remained a stable figure in Old Trafford and is still getting minutes, especially in cup competitions.
Paul Pogba (£ 89 million)
Easily the most commented and criticized transfer of modern Manchester United history. Pogba joined at a record rate of 93 million pounds from Juventus through the club's youth system and sold by peanuts compared to his return.
Love him or hate him, he has been an important element for the United team in recent seasons and has made some spectacular performances. Their problem has been consistency, and with their future constantly being speculated, their club days can be counted.

Romelu Lukaku (£ 75 million)
Lukaku's time at Manchester United divides opinions. Certain aspects of his game were scrutinized, but he scored 28 goals in 66 Premier League games for the club – an impressive return for any striker.
He was an effective but not aesthetic player, and his recent departure for Inter Milan was a disappointing end to his time at the club.
Fred (52 million pounds)
One of the lowest-expected transfers in recent seasons. For such a high rate, Fred should enter the starting eleven and form a formidable partnership with Paul Pogba.
However, his time at Old Trafford has been easy as he struggles to prove his worth and is lucky to have minutes with the aforementioned Pogba and young Scott McTominay.
Fred, 26, is not getting too many mini-shirts on a Man United shirt after a string of bad performances
Nemanja Matic (40 million pounds)
Matic was another midfield signing who never settled in the club. He previously had a good time at Chelsea, but when United offered £ 40m to the 28-year-old, the London club simply had to accept.
After a decent start, his time at Old Trafford was over and he failed to make a lasting impact.
TRUTH: JURY'S OUT
Victor Lindelof (£ 35 million)
The defender entered the tests and weathered the storm to maintain his place on the team.
Eric Bailly's recurring injury problems have helped the Swede become a cornerstone of the team and he seems to be growing as a player. Fans are excited about the new partnership with Harry Maguire and the future looks bright for the 25-year-old.
Lindelof is making steady improvements after joining United in summer 2017
Eric Bailly (£ 30 million)
The Ivorian joined United in 2016 and went straight to the start. However, it has been a picture of frustration since problems with injuries hindered its progress.
He is about to return to full fitness and faces stiff competition with Lindelof and Maguire, forming a strong bond.
TRUTH: JURY'S OUT
Henrikh Mkhitaryan (£ 30 million)
Armenian joined from Borussia …
