A 4-0 aggregate defeat to Barcelona in the Champions League exposed the gap Ole Gunnar Solskjaer must bridge to get Manchester United competing again.
There are a number of players with contracts running down and others who are not justifying their selections, leaving the Norwegian with decisions to make ahead of a crucial summer transfer window.
So who will still be a Manchester United player at the start of next season? Sportsmail assesses every member of the Reds' squad.
Ole Gunnar Solskjaer plans to overhaul Manchester United's squad to have them competing
David de Gea is one of a host of players that are seeing their contracts wind down to expiry
David de Gea - Jury's out
The Spanish goalkeeper is rightly considered one of the best in the world in his position. A rare error against Barcelona aside, he has been sensational for United in recent seasons.
His contract is running down and given he has not yet agreed a new deal, the club need to convince him or cash in before he winds it down to leave on a free.
Sergio Romero - Keep
The Argentine is one of the strongest No 2 stoppers in the league and appears content with life in Manchester.
He would make a reliable No 1 if De Gea does make a switch to Real Madrid in the summer.
Sergio Romero has proven to be one of the best No 2 goalkeeper's in the Premier League
Lee Grant - Jury's out
United's third goalkeeper is unlikely to be knocking on the door of boss Ole Gunnar Solskjaer asking for more minutes.
With two young goalkeepers out on loan the decision needs to be made whether the 36-year-old is surplus to requirements.
DEFENDERSVictor Lindelof - Keep
The Swedish international struggled initially having joined the club from Benfica but has now become the first choice centre back option.
Of all the defenders United could look to move on, Lindelof will not be the one they boot towards the exit.
Eric Bailly - Jury's out
Bailly started impressively when he joined from Villarreal but has struggled of late with both injury and form.
The Ivorian was Jose Mourinho's first signing but looks a shadow of the player that dominated those early matches. Serious work to do if he is to establish himself in the side once more.
Victor Lindelof started slowly at United but has become a mainstay under Solskjaer's reign
Phil Jones - Jury's out
Being turned inside out by Lionel Messi is nothing to be ashamed of but Phil Jones' time at the highest level must be under serious scrutiny.
Viewed as the 'next Duncan Edwards' when Sir Alex Ferguson snatched him from Blackburn Rovers, it simply has not worked out for the England international.
Chris Smalling - Keep
One of the most improved defenders at the club in recent years, Smalling, much like Lindelof, is under no immediate danger of being moved on.
Under contract until 2022 after netting an extension in December, can rest easy with other team-mates more at risk.
Marcos Rojo - Go
It is no secret that United need to move on one of the five centre backs currently at the club and Marcos Rojo seems to be front of that queue.
The Argentine told MUTV that he has been told he is in Solskjaer's plans but with the area in need of strengthening, his lack of minutes - largely due to injury - could prove costly.
Marcos Rojo has struggled to get a run in the team and could be set for a swift summer exit
Ashley Young - Go
It is not Ashley Young's fault that United's poor recruitment has seen him become a mainstay at full-back having started his career as a winger.
He lacks the pace to dominate at Champions League level and United can no longer afford to lean on Young. Having signed a new one-year deal in February, is likely being kept on as a valuable squad player and influence in the dressing room for the younger players.
Diogo Dalot - Keep
The Portuguese player is just 20 but has already shown glimpses of his potential - particularly in Europe.
Impressive in the 1-0 first leg defeat to Barcelona, he is the long-term option at right back and could make the position his own next season if the club fail to land Crystal Palace's Aaron Wan-Bissaka.
Luke Shaw - Keep
Jose Mourinho's departure breathed new life into Luke Shaw's Manchester United career and fans have begun to see the player they thought they had signed back in 2014.
He was the club's Player of the Month for March and is the undisputed first choice at left back. But the club need to bring in another left back to give the former Southampton player competition for places.
Antonio Valencia will leave on a free this summer with Diogo Dalot set to be the first choice
Antonio Valencia - Go
This has been confirmed by Solskjaer. The Ecuadorian has been colossal for United over the years but he is 33 now and with Dalot adapted to life in England, he has effectively been replaced by a younger model.
His contract expires in the summer and so it is an easy decision for United to pass up on negotiations for a new deal.
Matteo Darmian - Go
You have to feel sorry for Matteo Darmian that he has not been allowed to leave prior to this summer.
The Italian defender has plenty of interest in Serie A and given he is a free agent at the end of next
