With Louis van Gaal expected to be announced as the new manager soon, the performance this season shows that major changes need to be made to the Manchester United squad.

Whoever the new manager is, he should start by clearing out his current squad before bringing in replacements.

Here is a list of 10 players that Manchester United should sell this summer, (excluding players who have already agreed to leave the club).

1. Alex Buttner

The left-back was brought in to provide back-up for Patrice Evra but has failed to impress. His defensive contributions leave much to be desired and he has shown several times that he is nowhere near the level of the Frenchman.

Manchester United have been heavily linked with Southampton youngster Luke Shaw and this could prompt them to sell Buttner.

2.  Chris Smalling

Although he can play at either centre-back or right-back, Chris Smalling has struggled this season and looks short on confidence.

He is not as consistent as other defenders such as Phil Jones and isn't the world-class quality that Manchester United need if they are to seriously challenge for anything.

3. Tom Cleverley

Often the scapegoat and unfairly blamed for the team's poor performances, there is no denying that Tom Cleverley hasn't set the world alight since making his debut.

He was touted as a replacement for Paul Scholes in their midfield but doesn't add anything to the team in terms of goals, assists or defensive contribution.

4. Michael Carrick

Nobody can deny that Michael Carrick has been one of Manchester United's unsung heroes over the past few years. However, his form has waned desperately during this season as he has failed to provide a goal or assist at all this season.

He should be commended for what he has done at the club but now he needs to move on.

5. Anderson

Anderson was the subject of much speculation after bursting out of obscurity with a £20 million plus move to Manchester United. Since then, through numerous injuries and poor form, he has faded away and spent the second half of the season on loan at Fiorentina.

He is also quoted to have said that many players want away from Manchester United although he denies this.

6. Nani

This Portuguese trickster practically defines inconsistent. Being constantly compared to Cristiano Ronaldo may have hampered his progress but it is obvious that Nani has plenty of talent.

His hit and miss performances have bizarrely merited him a five-year contract so it seems that for the moment, Nani has a future at Old Trafford.

7. Ashley Young

With only two goals and one assist in the league this season, Ashley Young has struggled at Manchester United.

After his big money move from Aston Villa, Young's poor performances have seen him dropped from the England squad and playing a bit-part role at United. He should be sold to make way for a higher quality winger.

8. Shinji Kagawa

The golden boy of Dortmund hasn't shown his true potential at Manchester United since moving in 2012. He often cuts a frustrated figure and was benched a lot during David Moyes's time at the club.

Kagawa plays in the number 10 role, as an attacking midfielder behind the strikers but he faces strong competition for this role with Wayne Rooney and new arrival Juan Mata both preferred to him. With former club Dortmund interested in re-signing him, Kagawa may be tempted away from Manchester.

19. Javier Hernandez

Chicharito has had limited opportunities this season and when he has, he hasn't taken them. It is understood that he is frustrated about a lack of game-time and having to play as a fourth choice striker behind Van Persie, Rooney and Welbeck.

Could this signal an end to his time at Manchester United? There would be no shortage of clubs vying for the poacher's signature.

10. Robin van Persie

Sir Alex Ferguson always believed that no individual was bigger than the club he was at. It was this belief that prompted him to sell stars such as Roy Keane and Ruud van Nistelrooy. This makes us wonder if the new manager will have the same attitude towards Van Persie.

RVP has bemoaned his lack of service this season and seems to be blaming team mates and coaches for his poor goalscoring season, by his high standards. Although injuries have played a part, RVP still doesn't seem to have the same golden touch as last season and many will feel that he is just past his best.

However, if Louis van Gaal is appointed as expected, the former Netherlands coach will surely keep the talismanic Van Persie and try and get the best out of him for one more season.
