Manchester United's income has fallen following their failure to qualify for this season's Champions League.
The club's first-quarter revenue - to 30 September - was down £3.4m (2.8%), with matchday income suffering the biggest fall, down 32.3% to £16.8m.
The reduction is largely due to United playing three fewer home games compared to the same period 12 months ago.
Debt has risen 18% to £337.7m, largely due to the fall in the pound against the dollar since the Brexit vote.
Executive director Ed Woodward said: "Our financial results for this quarter reflect the impact of our non-participation in the Uefa Champions League.
