Manchester United have spent close to a staggering £1billion on transfers since Sir Alex Ferguson left the club at the end of the 2012/13 Premier League season.
Despite splashing out huge transfer fees, United have found themselves slowly slipping out of contention for titles, with rivals Manchester City spending similar money yet reaping the rewards in silverware.
Ferguson, who managed the club for 27 years, was replaced by David Moyes who had been in charge of Everton for 11 seasons.
Since then, Manchester United have been managed by Ryan Giggs as a caretaker, Louis van Gaal, Jose Mourinho and the current boss Ole Gunnar Solskjær.

David Moyes and a succession of managers have spent huge amounts at Manchester United
Juan Mata (£40 million)
The Spaniard joined from Premier League rivals Chelsea in very high regard as their Player of the Year for in the 2012-13 season, however, had fallen out of favour under new Chelsea manager at the time, Jose Mourinho.
Mata still regularly features in 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 squad since arriving in 2014.
Marouane Fellaini (£29 million)
The Belgian joined Manchester United on transfer deadline day in the summer of 2013.
He failed to make an impact under Moyes and the managers who followed and quickly became an impact substitute instead of a starter.
VERDICT: JURY'S OUT
Louis van Gaal
Angel Di Maria (£59.7 million)
The Argentine joined from Real Madrid with plenty of fanfare and the £59.7million was the highest ever fee paid by a British club at the time.
It's safe to say, his time in Manchester was not the best with just four goals in all competitions. He has since revived his career overseas as an integral part of the PSG squad.
Angel Di Maria had a torrid time at Manchester United, lasting just one Premier League season.
Anthony Martial (£36 million)
The Frenchman joined United in a deadline day scramble for a striker. There was plenty of pressure on Martial, who hit the ground running with three goals in his first two matches.
His time at the club has been largely frustrating; falling out of favour to Zlatan Ibrahimovic and Marcus Rashford under Jose Mourinho, but now he looks to be an important part of Ole Gunnar Solskjaer's plans going forward.
Morgan Schneiderlin (£31 million)
Another player from the van Gaal era that was meant to make a significant impact, but didn't. Signed from Southampton, the central midfielder was one of the hottest prospects in the Premier League but failed to show his worth in Manchester United red.
The 29-year-old has since left the club for Everton, where is still trying to re-find the form from his Southampton days.
Morgan Schneiderlin failed to make an impact at United and has since moved to Everton.
Luke Shaw (£30 million)
Luke Shaw had a hard time settling in at Manchester United due to injury problems in his first couple seasons. He looked destined for the door after he lost his place in the side to the likes of Daley Blind and Marcus Rojo but turned things around last season to win the club's player of the year accolade.
Shaw still has plenty of potential and has demonstrated great character to fight his way back into the squad.
VERDICT: JURY'S OUT
Ander Herrera (£28 million)
This was a hard fought transfer saga for United after having numerous bids rejected by Athletic Bilbao in David Moyes' reign.
Herrera added energy in the club's midfield and was an effective defensive screen in front of the back four. In the summer, he left the club and joined PSG on a free transfer in a move that left many Manchester United fans frustrated with his exit.
Ander Herrera made a positive impact in Manchester in his five-season stay at the club.
Memphis Depay (£25 million)
The Dutchman could not find his feet in England with just seven goals from 53 matches. He left the club to join Lyon where he has become one of the most dangerous forwards in European football.
Since leaving, Depay has been honest about his short time at United: 'I have no bitterness towards Mourinho. I think I was not good enough for him.'
Marcos Rojo (£16 million)
After reaching the 2014 World Cup final with Argentina, Rojo was on many club's watch-list but it was Louis van Gaal who snapped up the defender.
He joined on a five-year deal and hit the ground running, being able to play at left-back or centre-back. Since, he has become a lacklustre figure in the current squad and fans are unsure whether he is good enough.
VERDICT: JURY'S OUT
Marcos Rojo has been an indifferent signing for United, but still has the chance to improve.
Daley Blind (£13.8 million)
Blind joined the club having worked with Louis van Gaal previously for the Dutch national team.
While he never set the world alight, he was a solid player during his time at Old Trafford but slightly lost his way in the Mourinho era and now plays for Ajax. In today's market, £13.8 million seems more than reasonable for his contribution to the club.
Matteo Darmian (£12.7 million)
Darmian was an exciting acquisition when he was signed from Torino on a four-year contract. He had the perfect opportunity to become a regular in the side with Ashley Young and Antonio Valencia heading into the twilight of their careers.
Unfortunately, he has looked out of his depth at United and returned to Italy with Parma in the summer.
Matteo Darmian failed to take his chance and is now becoming an outcast at the club.
Bastian Schweinsteiger (£6.5 million)
For just £6.5 million, the German looked to be a fantastic piece of business. Sure he wasn't young, but he had unrivaled experience anchoring the Bayern Munich midfield to numerous trophies.
He showed glimpses of his ability but all too often looked off-the-pace at United and quickly went downhill as he was demoted to the Under-23 side before getting shipped to the MLS with Chicago Fire.
Radamel Falcao (£6 million, on loan)
Falcao joined Manchester United as one of the world's most famous and feared strikers and left a flop.
United fans believed Falcao would spearhead the attack that could win them another Premier League title, but it didn't quite work out that way. The Colombian scored just four goals before joining Chelsea on loan where he also failed to impress.
