Manchester United manager Louis van Gaal is reportedly preparing for a massive clear-out from his current roster at Old Trafford for the upcoming campaign.

The Daily Mirror reports that the Dutchman will show the door to 10 players, including his predecessor David Moyes' signing Marouane Fellaini, in the ongoing transfer window.

The other underperformers from the previous campaign who are believed to be in van Gaal's list are Nani, Ashley Young, Shinji Kagawa, Javier Hernandez, Tom Cleverley, Anderson, Wilfried Zaha, Bebe and Nick Powell.

The last two spent the entire last season away on loan at Pacos de Ferreira and Wigan Athletic, respectively, while Zaha moved to Cardiff City for the second-half of the campaign.

The remaining players had severely underperformed or had their chances restricted by the former Everton boss as the Red Devils finished a disappointing seventh in the Premier League. They will be without European football for the upcoming campaign and van Gaal is thought to be keen on reducing the wage bill to raise funds for four more signings.

The 62-year-old, who guided Netherlands to a third-place finish at the World Cup in Brazil, has already acquired the services of Ander Herrera and Luke Shaw from Athletic Bilbao and Southampton respectively.

United are said to be after Juventus' Chilean star Arturo Vidal although the Serie A champions have expressed their intentions to retain the 27-year-old midfielder.

The former Ajax, Barcelona and Bayern Munich boss was officially unveiled as manager on Wednesday and will be holding his first press-conference at Old Trafford on Thursday.

The Mirror's report also suggests that van Gaal wants to give the club's rising talents like Jesse Lingard, James Wilson and Tom Lawrence as well as brothers Michael and Will Keane an opportunity in the first team.

His first game in charge as Moyes' replacement will be against LA Galaxy on 23 July during the club's pre-season tour of the USA. The Dutchman will be expected to make an instant impact on the league as he will be looking to put United back among the top four in the table.
