Manchester United have never been scared to splash the cash on some of the world's best players. Having broken the English transfer record last year to sign Angel di Maria from Real Madrid, even the loss of Champions League football hasn't halted their expenditure.
But with a return of top level European action next term, Louis van Gaal will soon be looking ahead to next season's title race and will surely invest heavily in creating a team capable of claiming glory.
There is no doubt that United do boast some of the best players in the world, but they are still one or two signings away from attaining the Premier League title once more. With players like Robin van Persie, Radamel Falcao and Rafael da Silva looking set to leave Old Trafford, Van Gaal now has the issue with filling those gaps.
This season, United have lacked a striker that has been able to score on a consistent basis over a lengthy period of time. With Falcao not being able to settle into the team as well as United hoped and Van Persie struggling to maintain fitness, it is clear that another centre-forward is required.
Although Wayne Rooney has been playing up front of late, he does require a partner to work with. It seems that a marquee signing will be required to fill the spot. With the absence of having to pay Van Persie and Facao their massive salaries, it does seem possible.
In defence, United do need to find a right wing-back. Reports have linked Dani Alves and Nathaniel Clyne with moves to Old Trafford. Some would argue that Alves would be a good signing but not for the long-term.
Alves is definitely a player of quality and has huge amounts experience which would contribute to the development of the players United possess at the back, which is relatively young compared to a lot of the other big sides. Alves does seem as if he has passed his prime however, and would most likely ask for massive wages as it would probably be his last big move before he retires.
Clyne has had an exceptional season at Southampton and is becoming an excellent player. He is part of the defence that has conceded the least amount of goal of any team this season. Signing Clyne would make more sense for United as he is still young and has many years of service ahead of him.
If United are looking to buy foreign players in other positions, Clyne's home-grown status will be vital as well. The Saints will most likely demand a lot of money to prize him away from St Mary's but it's now a given between English clubs.
One thing we can expect is a lot of action happening around Old Trafford this summer with a lot of players also set to leave as well. United are definitely not out for the count and will be looking to land some knockout blows this summer.
