Since Ferguson called it a day in 2013, after 1,500 games in charge, the Red Devils have had four different permanent bosses.
They have also spent more than £800million on transfers with a net spend of £552million.
Despite the enormous amount spent on players, in the starting line-up against Barcelona, a game they lost 3-0, there were just four players signed in the post-Ferguson era.
The rest were either signings made by the legendary manager or have come through the youth ranks.
It perhaps illustrates the need for an extensive overhaul in the summer under new manager Ole Gunnar Solskjaer, something the boss has said is likely to happen.

Here is who lined-up against Barcelona on Tuesday.
David de Gea (Ferguson signing)
Signed by United in 2011 from Atletico Madrid for £18.9million and has gone on to play more than 300 times for the club.
Victor Lindelof (Mourinho signing)
The 24-year-old was one of Jose Mourinho’s first signings at the club for around £30.75million from Benfica.
Phil Jones (Ferguson signing)
After impressing with Blackburn as a teenager, he was snapped up by United in 2011 for £16.5million.
Chris Smalling (Ferguson signing)
The defender’s rise from non-league to Manchester United was quick. He went from Maidstone to the Red Devils, via Fulham within two years.
United paid around £12million for Smalling in 2010.
Ashley Young (Ferguson signing)
Young has transitioned from a winger to a defender over his United career.
He was signed for around £20million in 2011 from Aston Villa.
Paul Pogba (Mourinho signing)
A former United youth player who left the club in 2012 seeking first team opportunities.
He shined at Juventus and eventually was brought back to Old Trafford for £89.3million in 2016.
Jesse Lingard (From youth)
Lingard has been at the club since he was a seven-year-old and signed his first professional contract in 2011.
Fred (Mourinho signing)
United paid Shakhtar Donetsk around £52million for the Brazilian last summer but he has so far failed to live up to the price tag.
Scott McTominay (From youth)
Another product of the club’s youth set up – McTominay has been with the club since 2002 and signed his first professional deal in 2013.
