Manchester United's struggles have been well documented this season as the 20-time league champions continue to reel from the departure of Sir Alex Ferguson three years ago.
With their current side seemingly unable to recapture the lofty heights of previous generations, there is quite clearly a lot of work to be done at the club.
And it all begins this summer. Whether it's Louis van Gaal or Jose Mourinho in charge, United's manager must utilise the transfer funds given to them wisely if they're to re-establish themselves amongst Europe's elite. Here are five players they should look to sign.

Not a transfer windows goes by where United are not linked with Paris Saint-Germain's Cavani.
The Uruguayan goal-getter has been in Paris for three seasons now and performed admirably yet questions remain about his future at the Parc de Princes alongside first-choice striker Zlatan Ibrahimovic.
Now 29-years-old, Cavani would likely be available for less than PSG shelled out back in 2013 and given Wayne Rooney's erratic form in recent times, United need an experienced and quality marksman to lead the way alongside youngsters Anthony Martial and Marcus Rashford.
If United can’t get their hands on one PSG striker this summer, they may well move for another.
A statistic that will excite Red Devils fans is the fact Ibrahimovic has won the league title wherever he has played - something United crave following their decline in recent years.
He may be 35-years-old in October, but the Sweden international have never relied upon pace and instead utilised his intelligence and sheer power, suggested by his 36 goals scored in all competitions this season.
It remains to be seen just how committed Kane is to Tottenham Hotspur, but there's frankly little reason for him to leave given their exploits in the Premier League.
They also have one of the best managers in the business, with Mauricio Pochettino moulding a young and talented side arguably better than United's current crop of players.
However, the Red Devils remain the bigger and richer club of the two and a potential move to Old Trafford would still be hard to turn down for Kane.
In many ways, the England striker is the perfect signing: young, on his way to 'world-class' status and, of course, English. United would have to pay a huge sum to lure him from White Hart Lane, but if Kane's current form is anything to go by, they should do all they can to sign him this summer.
France international Raphael Varane was a firm favourite at Real Madrid under Mourinho, but since the Portuguese manager's departure, he has since slipped down the pecking order.
If Mourinho moves to Old Trafford this summer, then it seems entirely plausible that he could take the young centre-back with him - and even if Van Gaal remains in Manchester, he would be wise to try signing the classy 22-year-old.
It seems a move could be on the horizon too, with Varane recently voicing his desire to play for a club capable of offering more game time. Alongside Chris Smalling, United would have a solid centre-back partnership for years to come.
Aubameyang has been on fire this season, scoring a mammoth 36 goals in all competitions thus far and showing no signs of slowing down for Borussia Dortmund.
The Gabon international's electric form has seen him keep up with the clinical Robert Lewandowski in the Bundesliga goalscoring charts and establish himself as one of world football's most deadly strikers.
Dortmund will want to prevent against selling one of their prized assets, but if the price is right - and it doesn't involve Bayern Munich - they might just cash in.
