A major overhaul of the squad is the need of the hour at Old Trafford. After years of switching managers, bringing big-name players, it's time that Ed Woodward & co invest in the right kind of player.
It's no secret that the defence is in desperate need to get a new look. Ashley Young is past his prime and Antonio Valencia has left. Chris Smalling and Phil Jones have been at the club for a long time but haven't developed their game as Sir Alex Ferguson would have expected.
Along with that, right wing has been a huge problem. A club like Manchester United is surviving without a right winger for many seasons now. Juan Mata and Jesse Lingard have been deployed at that position lately but it's quite clear how dull they are on the flank.
Fresh blood is required in Manchester United and Ole Gunnar Solskjaer must be hoping that the board backs him. It's blatantly clear that Manchester United need at least 5 new faces when they start the new season if they aspire to challenge for any trophy.

#5 Kalidou Koulibaly
Koulibaly is among the top five centre-backs in the World currently. The 27-year old is the most essential part of Napoli's squad and they will be forced to fill a huge void if he opts to depart. He has played 48 games this season, making 1.8 tackles per game and 1.2 interceptions per game.
A move to Old Trafford has been linked for a while now but it's understood that the English club might have to break their transfer fee to sign the Senegalese centre-back.
Even though his market value is around £80 million, Napoli won't be willing to accept anything below £120 million considering the role the defender has played for them over the past few seasons.
How can he improve Manchester United?
Manchester United have been lining up without a solid right back for a while now. Only Lindelof has been the only player who has grown in stature during last season. Koulibaly could partner up with the Swedish centre-back to offer more security and reliability at the back. He has been one of the best Centre-backs in Serie A this season.
Unlike Chris Smalling and Phil Jones, his error-free passing could be of huge benefit for the football which Solskjaer wants his team to play. Lindelof is also a good ball distributor and adding Koulibaly could help United to play from the back.
#4 Aaron Wan-Bissaka
With Antonio Valencia's departure from Old Trafford, Ashley Young remains the only experienced campaigner for the right-back spot. But he endured a dismal season to say the least, both defensively and offensively.
Diogo Dalot is a promising talent but still needs to play as a squad player and earn experience before looking for a permanent berth in the starting XI. This leaves United short on options.
Aaron Wan-Bissaka could be their signing of the summer if they are successful in persuading him to the club. The 21-year old full back was arguably one of the best right-backs in Premier League this season. The Crystal Palace defender made astonishing 3.7 tackles per game and 2.4 interceptions per game.
Wan-Bissaka is in dreamland with a lot of big clubs seeking his signature. Manchester United is not in Champions League this season which could upset their plans. Wan-Bissaka may get calls from teams which are competing in the UCL.
How can he improve Manchester United?
Manchester United need a robust full-back like him who is not afraid of making challenges and has the stamina to run all day long.
Aaron Wan-Bissaka could be a perfect fit for Solskjaer system as he can defend well on one-on-one situation and can run into the opposition's half to deliver crosses.
#3 Declan Rice
Have a look over the options Manchester United has in centre midfield and you will know why we think that Declan Rice should be at Old Trafford next season. Nemanja Matic's game is fading. He is one of the slowest midfielders in the Premier League currently. United need more energy in that position.
Declan Rice has had a breakthrough season with Hammers. He played in the defensive midfield role for the whole season and even impressed Gareth Southgate to earn a national call-up.
Rice featured in 34 Premier League games for West Ham this season, making 2.9 tackles per game and having a passing success percentage of 86%. In addition, he also contributed by netting two goals.
Manuel Pellegrini admitted that it will be very tough for West Ham to desist Rice from leaving if any suitable offers come to the table.
How can he improve Manchester United?
Slowly and steadily, Declan Rice is getting better with his ball playing skills. Ole Gunner Solskjaer will prefer to have this young player in his team.
The England international can stay back and offer protection to the centre-defenders, which was duly missed last season. At the same time, he can give freedom to attacking players like Pogba and others to venture forward.
Rice hardly goes forward and leaves a big void in the middle. Hence, additional security in front of the defence could help United to decrease the number of goals they conceded this season.
#2 Moussa Dembele
The 22-year-old made a £19.7m move to Olympique Lyon from Celtic last summer and had an instant impact on his team's results. Moussa Dembele featured in 33 games including 21 starts, scoring 15 goals and assisting four times. Romelu Lukaku's uncertain future makes Dembele a good option for Solskjaer to boost his attacking options.
Dembele is strong and has a quick turn of pace. He is a typical number nine who likes to play short passes and also has a good eye for goals. According to many reports, Ole Gunnar Solskjaer led United has already made a bid to bring him to Old Trafford.
How can he improve Manchester United?
In a 4-3-1-2 system, Solskjaer can start with Dembele and Rashford up front. This will give them with a lot of speed in the final third. Both the young players have the ability to dribble past through the defenders.
Having Dembele will give Man United a player who can run directly towards the defenders. Considering the high prices prevailing in the transfer market, spending €40 million on Dembele could prove to be a bargain.
#1 Jadon Sancho
The 19-year-old England international had a mesmerizing season at Borussia Dortmund. Jadon Sancho has become a paradigm for youngsters who are not able to find game-time in the Premier League. His move from Manchester City to Dortmund have changed the whole complexion of his life. Sancho has become an integral part of the German outfit on the right side.
He has played in 34 Bundesliga games, scoring 12 goals and registering 14 assists. Jadon Sancho is a bright spark in the transfer market which lacks talented right wingers. His highly efficient and creative performances helped him to earn three international caps for England.
Even in this age, he has the ability to open up defences and run behind the defenders. The only thing which can attract him to move to Manchester is the rich history of the club as currently, Solskjaer's side is out of the Champions League.
How can he improve Manchester United?
Manchester United does not have any player whose preference is to play in that position. Signing Sancho, even if he is an expensive buy, will be very fruitful. Being only 19, he is a player who can be mainstay at Old Trafford for years to come.
Having fellow English Internationals like Marcus Rashford and Jesse Lingard could also help United to bring fluidity into the attack. He can feature in both 4-3-3 formation and can also play as a number 10 behind two strikers in a 4-3-1-2 formation.
