United's 1-1 draw at Chelsea on Sunday left them six points adrift of the Champions League qualification places with 13 matches left.
Louis van Gaal has faced questions about his position too, with Jose Mourinho reported to be ready to replace the beleaguered United boss if he is sacked, but off the pitch everything appears rosy.
United announced in their second-quarterly financial results on Thursday that they expect revenue for the year to hit £500-510million
No British club in history has recorded such a figure.
United announced a record second-quarter revenue total of £133.8million, up 26.6 per cent on last year.
Commercial revenue for the second quarter was £66.1million - an increase of 42.5 per cent on the previous year.
Broadcasting revenues were also up 31.3 per cent and sponsorship revenue for the second quarter was up £1.6million to £37.4million.
United executive vice-chairman Ed Woodward said: "Our strong commitment to investing in our squad, youth academy and the broader club are ultimately underpinned by our financial strength and the hard work and dedication of everyone at the club.
"Our solid results off the pitch help contribute to what remains our number one priority - success on the pitch."
Woodward will speak more about the results and field questions from investors during conference call at 1pm on Thursday.
