Manchester United and Ed Woodward have already been busy in the transfer market this time around, snapping up the signatures of Memphis Depay, Matteo Darmien, Bastian Schweinsteiger and Morgan Schneiderlin early on.
However, for them to become serious title contenders for the upcoming season, The Red Devils need to splash out even more cash in my opinion. Here are three players that i believe can take Manchester United to the next level and push them to become the best club in England once again.
Starting at the back, we all know the defensive concerns of Manchester United, even though their defensive record in the league isn't too bad with 37 goals conceded. You get the feeling that stat was largely down to their goalkeeper David de Gea.

The centre-backs at United simply aren't strong enough at the moment for the team to become a huge force in the world of football again.
What they need is a leader, a strong, committed, composed, player to fit in in front of de Gea, or whoever may be in-between the sticks come next season. What they need, is the German international Mats Hummels.
Experience is crucial when it comes to this position in the team, that's what United lacked last season and the season before after losing Nemanja Vidic. Hummels can definitely give them that.
The World Cup winner may only be 26-years-old, but his composure in sticky situations and positioning off the ball shows an individual that you would believe has been playing the game for many more years.
The Red Devils have been heavily linked with Sergio Ramos, but Real Madrid seem reluctant to sell the Spaniard and at 29-years-old, Hummels probably has a few more seasons left in him than the Los Blancos centre-back.
Hummels is the ultimate signing for United at the moment, he is someone who dominates the 18-yard-box from set-pieces. This is something United struggled with constantly last season due to arguable the lack of height.
The Dortmund player stands at around six feet three inches, making the spine of the squad formidable and is a strong replacement for the missed Vidic that United are yet to properly replace.
The next two players depend to the unknown formation of Louis van Gaal's side next season. United have plenty of central midfielders due to their most recent signings, so to overload that position even more would be borderline over-kill.
However, a position that may need strengthening in the midfield is the right-mid. Antonio Valencia spent a lot of his time last season in the right-wing-back slot due to Rafael's injury problems.
After that, United have no real contenders for the right-wing position after Nani has signed a deal with Turkish side Fernebahce along with Robin van Persie.
This position is actually a tough one to strengthen at the moment due to the lack of options The Red Devils have to bring in. Nevertheless, one affordable, realistic signing for United is another World Cup winner in the shape of Thomas Muller.
The German international is one of the most intelligent players in world football, as well as being one of the most versatile.
The Bayern Munich star can be used up-front, on the wings and even in centre-midfield if really needed. Muller netted 13 goals and bagged ten assists last season in the Bundesliga, and had a brilliant performance in Brazil at the World Cup.
Yes, United tried to sign Muller previously and failed to do so, however, the circumstances are much more tempting now for the 25-year-old winger.
United can offer Muller Champions League football, assuming they win their matches in the upcoming qualifiers, something they could not offer him last season.
Also, ex-teammate and compatriot Bastian Schweinsteiger is now at Old Trafford, so that could have a huge role to play. Muller is a world-class player that would offer United so many qualities, so if it's possible, make it happen United.
Finally, we come to the forwards. After Falcao's disappointing loan spell at Old Trafford, seeing him move onto rivals Chelsea, Van Persie's shock move to Fernebahce and Javier Hernandez' future unknown, United could be really struggling for strikers in the upcoming season.
Of course, the captain Wayne Rooney is a world-class striker and will surely lead the line next season, but depending on the formation played by Louis van Gaal, the Englishman may need a strike partner alongside him.
James Wilson may not be quite ready to be a first team player so soon, so Ed Woodward may be on the hunt for a big signing to play alongside the captain.
Edinson Cavani, Robert Lewandowski and Harry Kane have all been rumoured to be targets for United. However, I don't believe The Red Devils should sign any of these three individuals.
The player I think should start alongside Rooney next season if the formation requires it, is Alexandre Lacazette. The Frenchman has been heavily linked with a move to Arsenal, but i think United should beat them to it.
Lacazette netted a very impressive 27 goals and managed to get six assists while doing so in Ligue 1 last season. At 24-years-old, the Lyon striker has many years ahead of him and United do need to bring some youth into their first team at the moment, especially moving further up the field.
Lacazette would be a great partner for Rooney as they have different playing styles. Rooney's hold up play, strong running and range of passing is contrasted with Lacazette's electric pace running in behind the defence and cute finishing skills.
The two would complement each other's game a lot, the problem last season was that all the strikers had very similar playing styles and the forwards always used to want the ball played to feet.
Lacazette would provide the option for the through ball, which players like Rooney, Juan Mata, Angel Di Maria and Schweinsteiger can execute.
The 24-year-old would add a whole new dimension to United's game and while maybe he isn't as established as other striker targets for United, he certainly is as lethal.
As I mentioned before, Muller and Lacazette would only fit into the team if van Gaal played a certain formation next season. However, someone like Hummels is a player they need no matter what formation the team plays.
Of course, United may need to sign a keeper depending on de Gea's future, so that is another huge transfer that The Red Devils may need to make if the Spaniard does indeed leave Old Trafford.
If not however, the three signings I have just mentioned would make United into serious title challengers and who knows, even potential Champions League winners in the upcoming season.
