Manchester United's share price has taken a staggering hit overnight with the Premier League side's biggest drop in a year wiping more than £300million off the club's overall value.
The latest New York Stock Exchange (NYSE) figures has seen Manchester United's share price drop to its lowest point since October 2017.
Their share price fail to $18.19 (£14.22) from $19.92 (£15.58) before the NYSE shut on Tuesday evening.
Despite the dramatic fall, United's top brass have said the Glazer family are relaxed about the situation at the club.
They have put the slump down to the market rather than results affecting their value away from the football pitch.
On the pitch, United have struggled for form in the Premier League with the Red Devils languishing in eighth spot after 12 games.
United have lost six of their 12 top-flight games with their latest defeat coming at the hands of rivals Manchester City before the international break.
Meanwhile, their wage bill has increased by more than 10 per cent, despite the club's poor start to the season.
Figures released on Thursday for the first quarter of 2018 show that 'employee benefit expenses' for the three-month period were £77million, an increase of £7.1 million, or 10.2 per cent, over last year - which they say is 'primarily due to investment in the first team playing squad'.
It means Mourinho's men are set to earn around £308m this season, which gives them by far the biggest wage bill in the Premier League.
The figures also show that, despite a quarterly drop in commercial and sponsorship money, United continue to expect annual revenue to be between £615m to £630m, which would represent a new record.
It is thought that the losses in matchday, commercial and sponsorship revenue are down to a shorter summer tour and fewer number of home matches being played compared with the same reporting period last year.
Ed Woodward, United's executive vice chairman, said: 'Our financial strength enables us to continue to attract and retain top players and to invest in our academy, as we look to drive the success on the pitch that the club and our fans expect.
'We remain on track to deliver our record full-year revenue guidance, underpinning our long-term, strategic plan to create sustainable growth across all areas of the club.'
United confirmed on Tuesday that they will be touring Australia ahead of next season.
They will face bitter rivals Leeds and Perth Glory during the pre-season trip.
