The value of Manchester United has dropped by £400m over the course of the season, stock market figures have suggested.

According to the figures cited by Sky Sports News, the team's share price has fallen from $18.37 (£12.84) at the start of the season to $13.83 (£9.67) by the time the New York Stock Exchange closed on Monday.

The drop in share price of around 25% means that the club's effective valuation has tumbled from £2bn to £1.58 bn over the course of the campaign.

The news is likely to further increase the pressure on troubled manager Louis van Gaal, who is facing a fight to qualify for next season's Champions League having seen his side surrender a top-four place and crash out of this season's competition in December.

United's hunt for silverware could be ended tonight as they travel to West Ham United looking for a place in the semi-finals of the FA Cup.

Despite the drop in share price, United remain on course to usurp Real Madrid as the world's richest club thanks to commercial revenues from a new Adidas kit deal and other strategic partnerships.
