Here are four players who United must decide what to do with over the summer.
Young central midfield Brazilian Anderson was signed from Porto in May 2007 for £20.4 million. He was seen as the ideal replacement for Paul Scholes.
However, his fitness and form have declined rapidly. The 24 year old became United's second Brazilian player after Kleberson and has done little do distance him from being known as one who failed to make the cut.
Earlier on in his United career he was known for his vision, adept tackling ability, and being strong, tireless and hard-working. Unfortunately injury may have caused a downward spiral to his career but it has to be said that in too many games Anderson has found himself exposed and ineffective enabling the likes of Michael Carrick, Tom Cleverely and the re emergence of Paul Scholes to get ahead of him in United’s starting lineup.
His poor return of 4 goals in 83 appearances is another concern as central midfielders should provide large chunks of team’s goals, which is something that hasn’t appeared with Anderson. Should Manchester United stick with him or sell?
United’s number 7 (a shirt previously worn by Cristiano Ronaldo) has found himself becoming the new Owen Hargreaves of Manchester United.
Owen has been inundated with injuries throughout his Manchester United career. A return of five goals in thirty- one appearances is poor for a player who was one of the most feared strikers in the game.
With the emergence of Javier Hernandez and Danny Welbeck alongside the established Wayne Rooney, Owen's chances at United look limited at best.
Park signed for United side for £4 million in 2005 and has had many standout moments, with crucial goals against Arsenal, Chelsea and Liverpool in his time at Old Trafford.
The former South Korean captain has become known as 'three lungs Park' to United fans due to his tireless effort, superior fitness and relentless work rate.
This season he has seen his career at Manchester United stall. Park has become more of a fringe player than a big game player, and it seems as though his time at United is coming to an end, even though a poll on this website revealed 66 per cent of supporters want to keep him.
The signings of Young, Valencia, and return of Scholes have seen Park used sparingly by Sir Alex Ferguson. It may be wise if United move the player on and can arrange some sort of fee than allow him to leave on a free.
Federico "Kiko" Macheda joined Manchester United from Lazio for an undisclosed fee in September 2007- and is still only 20.
He will always be remembered for scoring the winning goal in a match against Aston Villa 2009 with a delightful curling effort from just inside the penalty area in the third minute of injury time. However, apart from that what else has the young Italian offered?
This weekend's home game against Villa at a similarly late crucial time of the season was a stark reminder of how the promising striker's career has failed to ignite since.
He has had two unsuccessful loans- at Sampdoria who were relegated to Serie B, and Queens Park Rangers, who continue to fight it without him after sitting on the bench and sustaining an ankle injury before being sent back to Old Trafford.
It sounds like Sir Alex Ferguson is torn over what to do with him. "He is so unlucky, I have complete belief in the boy. He could be an outstanding player. But he needs football."
The question is, will that be at Old Trafford or elsewhere?
Do you agree United should move these four on? Which ones should they keep?
