If David Moyes manages to retain his job before the start of next season, he will have one heck of a job on his hands this summer.
Nemanja Vidic has announced his intention to quit the club at the end of the campaign, while others are tipped to follow.
Moyes will need to splash some serious cash to make sure United are competitive again next season, but which five players should he purchase to fill the club’s problem positions?
Left-back: Ben Davies | Swansea City
Patrice Evra is likely to leave Old Trafford when his contract expires at the end of the season and Alexander Buttner simply isn’t of sufficient quality, so who should David Moyes bring in as his new first-choice left-back?
Southampton’s Luke Shaw would be perfect; however, the English youngster apparently has his heart set on a move to Chelsea. Meanwhile, Leighton Baines has signed a new contract at Everton, and there are doubts about whether Real Madrid’s Fabio Coentrao would be the right man for the job.
One player who would be ideal for the job if Ben Davies of Swansea City. The 20-year-old Wales international has been superb for the Swans over the last 18 months and has an incredibly bright future ahead of him.
Centre-back: Eliaquim Mangala | FC Porto
Manchester United captain Nemanja Vidic will leave the Red Devils at the end of the season, while there are doubts about Rio Ferdinand’s future at the club, too.
David Moyes would still have Jonny Evans, Chris Smalling and Phil Jones at his disposal if both players departed, but it’s clear that another top-class centre-back is required.
Eliaquim Mangala, 22, is likely to cost a fortune - but shelling out for the FC Porto defender would be worth it in the long run.
Central midfielder: Ilkay Gundogan | Borussia Dortmund
Okay, so the last time Manchester United signed a star from Borussia Dortmund it didn’t pan out as well as hoped; however, whereas United have struggled to accommodate Shinji Kagawa in his favoured No. 10 position, there’s no doubt Ilkay Gundogan would walk straight into the Red Devils’ midfield.
The 23-year-old is an immensely talented footballer who would improve Manchester United considerably.
Juventus star Arturo Vidal would be another fantastic acquisition, but a move for Germany international Gundogan is perhaps a little more likely.
Winger: Adam Lallana | Southampton
Antonio Valencia has failed to perform well on a consistent basis for far too long now, while Wilfried Zaha does not appear to be David Moyes’ cup of tea - at least for the time being.
Adam Lallana, therefore, could be the man to nail down United’s attacking wide-right position.
The 25-year-old is improving all the time, and has enjoyed a superb season on the south coast with Southampton.
Expect his price to rise, however, after the 2014 World Cup finals in Brazil.
Striker: Edinson Cavani | Paris Saint-Germain
Rumours suggest that Edinson Cavani isn’t particularly happy at Paris Saint-Germain - and that both Manchester United and Chelsea are keen on the 26-year-old.
Cavani is a striker of world-class quality and would be an upgrade on the ageing and injury-prone Robin van Persie, who is four years Cavani’s senior.
United would need to pay over £50m to sign the Uruguay international, but they would be signing a striker who would bag them 20+ goals every season.
