The future of Manchester United manager Louis van Gaal has been placed in further doubt after the Dutchman was left out of the club's promotional video for the summer tour of China.

Van Gaal's position at Old Trafford has been the subject of continued speculation with former Chelsea manager Jose Mourinho tipped to take over.

Van Gaal will soon enter the final year of a three-year contract to manage the Red Devils but was left out of a 48-second clip on the club website to promote the summer trip to the Far East.

The video featured 14 members of the current squad and several former players.

The video for last summer's tour to the United States featured Van Gaal prominently but his position has come under pressure with the team now out of Europe and not featuring in the Premier League title race.

United's hopes of a top-four finish and Champions League qualification for next season were boosted by victory in the Manchester derby on Sunday and they face West Ham in an FA Cup quarter-final replay on 13 April.

But leaving Van Gaal out of the promotional video for the International Champions Cup games against Borussia Dortmund in Shanghai on 22 July and Manchester City in Beijing three days later has added to speculation that the Dutchman could be on his way out.
